Problem
You are given an array of two strings, both strings consist of open
parentheses '(' or close parentheses ')' only.
Your job is to check if it is possible to concatenate the two strings in
some order, that the resulting string will be good.
A string S is considered to be good if and only if all parentheses in S
are balanced. For example: the string '(())()' is good, while the string
'())' is not.
Return 'Yes' if there's a way to make a good string, and return 'No' otherwise.
Examples:
matchParens(lst: ["()(", ")"]) == "Yes"
matchParens(lst: [")", ")"]) == "No"
func matchParens(lst: [String]) -> String { ...
XCTAssertTrue(matchParens(lst: ["()(", ")"]) == "Yes")
XCTAssertTrue(matchParens(lst: [")", ")"]) == "No")
XCTAssertTrue(matchParens(lst: ["(()(())", "())())"]) == "No")
XCTAssertTrue(matchParens(lst: [")())", "(()()("]) == "Yes")
XCTAssertTrue(matchParens(lst: ["(())))", "(()())(("]) == "Yes")
XCTAssertTrue(matchParens(lst: ["()", "())"]) == "No")
XCTAssertTrue(matchParens(lst: ["(()(", "()))()"]) == "Yes")
XCTAssertTrue(matchParens(lst: ["((((", "((())"]) == "No")
XCTAssertTrue(matchParens(lst: [")(()", "(()("]) == "No")
XCTAssertTrue(matchParens(lst: [")(", ")("]) == "No")
XCTAssertTrue(matchParens(lst: ["(", ")"]) == "Yes")
XCTAssertTrue(matchParens(lst: [")", "("]) == "Yes")

Write code in Swift programming language. Don't include usage examples or tests.
You are given an array of two strings, both strings consist of open
parentheses '(' or close parentheses ')' only.
Your job is to check if it is possible to concatenate the two strings in
some order, that the resulting string will be good.
A string S is considered to be good if and only if all parentheses in S
are balanced. For example: the string '(())()' is good, while the string
'())' is not.
Return 'Yes' if there's a way to make a good string, and return 'No' otherwise.

You are given an array of two strings, both strings consist of open
parentheses '(' or close parentheses ')' only.
Your job is to check if it is possible to concatenate the two strings in
some order, that the resulting string will be good.
A string S is considered to be good if and only if all parentheses in S
are balanced. For example: the string '(())()' is good, while the string
'())' is not.
Return 'Yes' if there's a way to make a good string, and return 'No' otherwise.
Examples:
matchParens(lst: ["()(", ")"]) == "Yes"
matchParens(lst: [")", ")"]) == "No"

A string S is considered to be good if and only if all parentheses in S
are balanced. For example: the string '(())()' is good, while the string
'())' is not.
Return 'Yes' if there's a way to make a good string, and return 'No' otherwise.
Examples:
matchParens(lst: ["()(", ")"]) == "Yes"
matchParens(lst: [")", ")"]) == "No"
Answer:
```swift
func matchParens(lst: [String]) -> String {
let stack = [Character]()
for str in lst {
for char in str {
switch char {
case "(":
stack.append(char)
case ")":
if stack.isEmpty || stack.last!= "(" {
return "No"
}
stack.removeLast()
default:
return "No"
}
}
}
return stack.isEmpty? "Yes" : "No"
}
```
stack.append(char) // cannot use mutating member on immutable value: 'stack' is a 'let' constant
if stack.isEmpty || stack.last!= "(" { // expression is not assignable: '||' returns immutable value
if stack.isEmpty || stack.last!= "(" { // cannot convert value of type 'Character' to expected argument type 'Bool'

parentheses '(' or close parentheses ')' only.
Your job is to check if it is possible to concatenate the two strings in
some order, that the resulting string will be good.
A string S is considered to be good if and only if all parentheses in S
are balanced. For example: the string '(())()' is good, while the string
'())' is not.
Return 'Yes' if there's a way to make a good string, and return 'No' otherwise.
Examples:
matchParens(lst: ["()(", ")"]) == "Yes"
matchParens(lst: [")", ")"]) == "No"
Answer:
```swift
func matchParens(lst: [String]) -> String {
var stack = [Character]()
var openParens = 0
var closeParens = 0
for string in lst {
for char in string {
if char == "(" {
openParens += 1
stack.append(char)
} else if char == ")" {
closeParens += 1
if stack.isEmpty || stack.removeLast()!= "(" {
return "No"
}
}
}
}
if openParens == closeParens {
return "Yes"
} else {
return "No"
}
}
```
if stack.isEmpty || stack.removeLast()!= "(" { // expression is not assignable: '||' returns immutable value
if stack.isEmpty || stack.removeLast()!= "(" { // cannot force unwrap value of non-optional type 'Character'
if stack.isEmpty || stack.removeLast()!= "(" { // use of '=' in a boolean context, did you mean '=='?
if stack.isEmpty || stack.removeLast()!= "(" { // '=' must have consistent whitespace on both sides
if stack.isEmpty || stack.removeLast()!= "(" { // cannot convert value of type 'Character' to expected argument type 'Bool'
func matchParens(lst: [String]) -> String {
var stack = [Character]()
let str = lst.joined()
for char in str {
if char == "(" {
stack.append(char)
} else if char == ")" {
if stack.isEmpty || stack.last!= "(" {
return "No"
}
stack.removeLast()
}
}
return stack.isEmpty? "Yes" : "No"

parentheses '(' or close parentheses ')' only.
Your job is to check if it is possible to concatenate the two strings in
some order, that the resulting string will be good.
A string S is considered to be good if and only if all parentheses in S
are balanced. For example: the string '(())()' is good, while the string
'())' is not.
Return 'Yes' if there's a way to make a good string, and return 'No' otherwise.
Examples:
matchParens(lst: ["()(", ")"]) == "Yes"
matchParens(lst: [")", ")"]) == "No"
Answer:
```swift
func matchParens(lst: [String]) -> String {
var stack = [Character]()
for char in lst {
if char == "(" {
stack.append(")")
} else if char == ")" {
if stack.isEmpty || stack.pop()!= ")" {
return "No"
}
}
}
return stack.isEmpty? "Yes" : "No"
}
```
if stack.isEmpty || stack.pop()!= ")" { // '=' must have consistent whitespace on both sides
if stack.isEmpty || stack.pop()!= ")" { // use of '=' in a boolean context, did you mean '=='?
if stack.isEmpty || stack.pop()!= ")" { // value of type '[Character]' has no member 'pop'
return stack.isEmpty? "Yes" : "No" // string literal is unused
return stack.isEmpty? "Yes" : "No" // expected expression
return stack.isEmpty? "Yes" : "No" // cannot use optional chaining on non-optional value of type 'Bool'
return stack.isEmpty? "Yes" : "No" // consecutive statements on a line must be separated by ';'
return stack.isEmpty? "Yes" : "No" // consecutive statements on a line must be separated by ';'
func matchParens(lst: [String]) -> String {
var stack = [Character]()
for char in lst {
if char == "(" {
stack.append(char)
} else {
if stack.count == 0 {
return "No"
}
stack.removeLast()
}
}
return stack.count == 0? "Yes" : "No"
}

Write code in Swift programming language. Don't include usage examples or tests.
You are given an array of two strings, both strings consist of open
parentheses '(' or close parentheses ')' only.
Your job is to check if it is possible to concatenate the two strings in
some order, that the resulting string will be good.
A string S is considered to be good if and only if all parentheses in S
are balanced. For example: the string '(())()' is good, while the string
'())' is not.
Return 'Yes' if there's a way to make a good string, and return 'No' otherwise.

### Instruction:
Write code in Swift programming language. Don't include usage examples or tests.
You are given an array of two strings, both strings consist of open
parentheses '(' or close parentheses ')' only.
Your job is to check if it is possible to concatenate the two strings in
some order, that the resulting string will be good.
A string S is considered to be good if and only if all parentheses in S
are balanced. For example: the string '(())()' is good, while the string
'())' is not.
Return 'Yes' if there's a way to make a good string, and return 'No' otherwise.
Examples:
matchParens(lst: ["()(", ")"]) == "Yes"
matchParens(lst: [")", ")"]) == "No"

You are given an array of two strings, both strings consist of open
parentheses '(' or close parentheses ')' only.
Your job is to check if it is possible to concatenate the two strings in
some order, that the resulting string will be good.
A string S is considered to be good if and only if all parentheses in S
are balanced. For example: the string '(())()' is good, while the string
'())' is not.
Return 'Yes' if there's a way to make a good string, and return 'No' otherwise.
Examples:
matchParens(lst: ["()(", ")"]) == "Yes"
matchParens(lst: [")", ")"]) == "No"
### Response:
```swift
func matchParens(lst: [String]) -> String {
let combined = lst.joined()
var stack: [Character] = []
for char in combined {
if char == "(" {
stack.append(char)
} else if char == ")" {
if stack.isEmpty || stack.last != "(" {
return "No"
} else {
stack.removeLast()
}
}
}
return stack.isEmpty ? "Yes" : "No"
}

Write code in Swift programming language. Don't include usage examples or tests.
You are given an array of two strings, both strings consist of open
parentheses '(' or close parentheses ')' only.
Your job is to check if it is possible to concatenate the two strings in
some order, that the resulting string will be good.
A string S is considered to be good if and only if all parentheses in S
are balanced. For example: the string '(())()' is good, while the string
'())' is not.
Return 'Yes' if there's a way to make a good string, and return 'No' otherwise.

Your job is to check if it is possible to concatenate the two strings in
some order, that the resulting string will be good.
A string S is considered to be good if and only if all parentheses in S
are balanced. For example: the string '(())()' is good, while the string
'())' is not.
Return 'Yes' if there's a way to make a good string, and return 'No' otherwise.

matchParens(lst: ["()(", ")"]) == "Yes"

You are given an array of two strings, both strings consist of open
parentheses '(' or close parentheses ')' only.
Your job is to check if it is possible to concatenate the two strings in
some order, that the resulting string will be good.
A string S is considered to be good if and only if all parentheses in S
are balanced. For example: the string '(())()' is good, while the string
'())' is not.
Return 'Yes' if there's a way to make a good string, and return 'No' otherwise.

### Instruction:
Write code in Swift programming language. Don't include usage examples or tests.
You are given an array of two strings, both strings consist of open
parentheses '(' or close parentheses ')' only.
Your job is to check if it is possible to concatenate the two strings in
some order, that the resulting string will be good.
A string S is considered to be good if and only if all parentheses in S
are balanced. For example: the string '(())()' is good, while the string
'())' is not.
Return 'Yes' if there's a way to make a good string, and return 'No' otherwise.
Examples:
matchParens(lst: ["()(", ")"]) == "Yes"
matchParens(lst: [")", ")"]) == "No"
### Response:
```swift
func matchParens(lst: [String]) -> String {
let first = lst[0]
let second = lst[1]
var count = 0
for char in first {
if char == "(" {
count += 1
} else {
count -= 1
}
if count < 0 {
return "No"
}
}
count = 0
for char in second {
if char == ")" {
count += 1
} else {
count -= 1
}
if count < 0 {
return "No"
}
}
return "Yes"
}

This code defines a function `matchParens` that takes a list of two strings as input and returns a string indicating whether it is possible to concatenate the strings in some order to form a good string.
The function works by iterating over the characters of both strings and keeping track of the number of open parentheses and the number of close parentheses. If at any point the number of open parentheses is greater than the number of close parentheses, it means that the string is not good and the function returns "No". If the end of both strings is reached without any mismatches, it means that the string is good and the function returns "Yes".
Note: The code assumes that the input list will always contain exactly two strings. If the list contains more or fewer strings, the function may not work as expected.

This code defines a function `matchParens` that takes a list of strings `lst` as input and returns a string indicating whether it is possible to concatenate the strings in some order to form a good string.
The function iterates over each string in `lst` and counts the number of open and close parentheses. If the number of open parentheses is ever greater than the number of close parentheses, the string is not good, and the function returns "No". If the loop completes without finding an invalid string, the function returns "Yes".
The function assumes that the input list `lst` contains only strings consisting of open and close parentheses.
Note: This solution is NOT OPTIMAL.

This code defines a function `matchParens` that takes a list of strings `lst` as input and returns a string indicating whether it is possible to concatenate the strings in some order to form a good string.
The function works by iterating over each string in `lst` and counting the number of open and close parentheses. If the number of open parentheses is ever greater than the number of close parentheses, the function returns "No" since it's not possible to have a good string with more open parentheses than close parentheses.
If the iteration completes without finding an invalid string, the function returns "Yes", indicating that it is possible to concatenate the strings in some order to form a good string.
Note: This solution assumes that the input list `lst` contains only strings consisting of open and close parentheses. If the list contains other characters, the function may not behave as expected.

This code defines a function `matchParens` that takes an array of two strings as input and returns a string indicating whether it is possible to concatenate the strings in some order to form a good string.
The function assumes that the input strings consist only of open parentheses '(' and close parentheses ')'. It checks if it is possible to concatenate the strings in some order to form a good string by ensuring that the number of open parentheses is always greater than or equal to the number of close parentheses at any given time.
The function returns "Yes" if it is possible to concatenate the strings to form a good string, and "No" otherwise.
Note: The code assumes that the input strings are valid and contain only parentheses. If the input is invalid, the behavior is not defined.

You are given an array of two strings, both strings consist of open
parentheses '(' or close parentheses ')' only.
Your job is to check if it is possible to concatenate the two strings in
some order, that the resulting string will be good.
A string S is considered to be good if and only if all parentheses in S
are balanced. For example: the string '(())()' is good, while the string
'())' is not.
Return 'Yes' if there's a way to make a good string, and return 'No' otherwise.

You are given an array of two strings, both strings consist of open
parentheses '(' or close parentheses ')' only.
Your job is to check if it is possible to concatenate the two strings in
some order, that the resulting string will be good.
A string S is considered to be good if and only if all parentheses in S
are balanced. For example: the string '(())()' is good, while the string
'())' is not.
Return 'Yes' if there's a way to make a good string, and return 'No' otherwise.

You are given an array of two strings, both strings consist of open
parentheses '(' or close parentheses ')' only.
Your job is to check if it is possible to concatenate the two strings in
some order, that the resulting string will be good.
A string S is considered to be good if and only if all parentheses in S
are balanced. For example: the string '(())()' is good, while the string
'())' is not.
Return 'Yes' if there's a way to make a good string, and return 'No' otherwise.
Examples:
matchParens(lst: ["()(", ")"]) == "Yes"
matchParens(lst: [")", ")"]) == "No"
Answer:
```swift
func matchParens(lst: [String]) -> String {
var stack = [Character]()
for str in lst {
for char in str {
if char == "(" {
stack.append(char)
} else {
if stack.isEmpty {
return "No"
}
stack.removeLast()
}
}
}
return stack.isEmpty? "Yes" : "No"
}
```
return stack.isEmpty? "Yes" : "No" // consecutive statements on a line must be separated by ';'
return stack.isEmpty? "Yes" : "No" // string literal is unused
return stack.isEmpty? "Yes" : "No" // expected expression
return stack.isEmpty? "Yes" : "No" // consecutive statements on a line must be separated by ';'
return stack.isEmpty? "Yes" : "No" // cannot use optional chaining on non-optional value of type 'Bool'

You are given an array of two strings, both strings consist of open
parentheses '(' or close parentheses ')' only.
Your job is to check if it is possible to concatenate the two strings in
some order, that the resulting string will be good.
A string S is considered to be good if and only if all parentheses in S
are balanced. For example: the string '(())()' is good, while the string
'())' is not.
Return 'Yes' if there's a way to make a good string, and return 'No' otherwise.
Examples:
matchParens(lst: ["()(", ")"]) == "Yes"
matchParens(lst: [")", ")"]) == "No"

### Instruction:
Write code in Swift programming language. Don't include usage examples or tests.
You are given an array of two strings, both strings consist of open
parentheses '(' or close parentheses ')' only.
Your job is to check if it is possible to concatenate the two strings in
some order, that the resulting string will be good.
A string S is considered to be good if and only if all parentheses in S
are balanced. For example: the string '(())()' is good, while the string
'())' is not.
Return 'Yes' if there's a way to make a good string, and return 'No' otherwise.
Examples:
matchParens(lst: ["()(", ")"]) == "Yes"
matchParens(lst: [")", ")"]) == "No"

You are given an array of two strings, both strings consist of open
parentheses '(' or close parentheses ')' only.
Your job is to check if it is possible to concatenate the two strings in
some order, that the resulting string will be good.
A string S is considered to be good if and only if all parentheses in S
are balanced. For example: the string '(())()' is good, while the string
'())' is not.
Return 'Yes' if there's a way to make a good string, and return 'No' otherwise.

matchParens(lst: ["()(", ")"]) == "Yes"
matchParens(lst: [")", ")"]) == "No"<|im_end|>

You are given an array of two strings, both strings consist of open
parentheses '(' or close parentheses ')' only.
Your job is to check if it is possible to concatenate the two strings in
some order, that the resulting string will be good.
A string S is considered to be good if and only if all parentheses in S
are balanced. For example: the string '(())()' is good, while the string
'())' is not.
Return 'Yes' if there's a way to make a good string, and return 'No' otherwise.

matchParens(lst: ["()(", ")"]) == "Yes"
matchParens(lst: [")", ")"]) == "No"

Question:
Write code in Swift programming language. Don't include usage examples or tests.
You are given an array of two strings, both strings consist of open
parentheses '(' or close parentheses ')' only.
Your job is to check if it is possible to concatenate the two strings in
some order, that the resulting string will be good.
A string S is considered to be good if and only if all parentheses in S
are balanced. For example: the string '(())()' is good, while the string
'())' is not.
Return 'Yes' if there's a way to make a good string, and return 'No' otherwise.
Examples:
matchParens(lst: ["()(", ")"]) == "Yes"
matchParens(lst: [")", ")"]) == "No"
Answer:
```swift
func matchParens(lst: [String]) -> String {
var stack = [Character]()
for char in lst {
if char == "(" {
stack.append(char)
} else if char == ")" {
if stack.isEmpty {
return "No"
} else {
stack.removeLast()
}
}
}
return stack.isEmpty? "Yes" : "No"
}
```
stack.append(char) // no exact matches in call to instance method 'append'
return stack.isEmpty? "Yes" : "No" // cannot use optional chaining on non-optional value of type 'Bool'
return stack.isEmpty? "Yes" : "No" // expected expression
return stack.isEmpty? "Yes" : "No" // string literal is unused

Question:
Write code in Swift programming language. Don't include usage examples or tests.
You are given an array of two strings, both strings consist of open
parentheses '(' or close parentheses ')' only.
Your job is to check if it is possible to concatenate the two strings in
some order, that the resulting string will be good.
A string S is considered to be good if and only if all parentheses in S
are balanced. For example: the string '(())()' is good, while the string
'())' is not.
Return 'Yes' if there's a way to make a good string, and return 'No' otherwise.
Examples:
matchParens(lst: ["()(", ")"]) == "Yes"
matchParens(lst: [")", ")"]) == "No"
Answer:
```swift
func matchParens(lst: [String]) -> String {
var count = 0
for c in lst[0] {
if c == "(" {
count += 1
} else {
count -= 1
}
if count < 0 {
return "No"
}
}
count = 0
for c in lst[1] {
if c == "(" {
count += 1
} else {
count -= 1
}
if count < 0 {
return "No"
}
}
if count == 0 {
return "Yes"
} else {
return "No"
}
}
```

You are given an array of two strings, both strings consist of open
parentheses '(' or close parentheses ')' only.
Your job is to check if it is possible to concatenate the two strings in
some order, that the resulting string will be good.
A string S is considered to be good if and only if all parentheses in S
are balanced. For example: the string '(())()' is good, while the string
'())' is not.
Return 'Yes' if there's a way to make a good string, and return 'No' otherwise.

### Instruction:
Write code in Swift programming language. Don't include usage examples or tests.
You are given an array of two strings, both strings consist of open
parentheses '(' or close parentheses ')' only.
Your job is to check if it is possible to concatenate the two strings in
some order, that the resulting string will be good.
A string S is considered to be good if and only if all parentheses in S
are balanced. For example: the string '(())()' is good, while the string
'())' is not.
Return 'Yes' if there's a way to make a good string, and return 'No' otherwise.
Examples:
matchParens(lst: ["()(", ")"]) == "Yes"
matchParens(lst: [")", ")"]) == "No"
### Response:

### Instruction:
Write code in Swift programming language. Don't include usage examples or tests.
You are given an array of two strings, both strings consist of open
parentheses '(' or close parentheses ')' only.
Your job is to check if it is possible to concatenate the two strings in
some order, that the resulting string will be good.
A string S is considered to be good if and only if all parentheses in S
are balanced. For example: the string '(())()' is good, while the string
'())' is not.
Return 'Yes' if there's a way to make a good string, and return 'No' otherwise.
Examples:
matchParens(lst: ["()(", ")"]) == "Yes"
matchParens(lst: [")", ")"]) == "No"

A string S is considered to be good if and only if all parentheses in S
are balanced. For example: the string '(())()' is good, while the string
'())' is not.
Return 'Yes' if there's a way to make a good string, and return 'No' otherwise.
Examples:
matchParens(lst: ["()(", ")"]) == "Yes"
matchParens(lst: [")", ")"]) == "No"
### Response:
```swift
func matchParens(lst: [String]) -> String {
// Write your code here
var stack = [Character]()
for char in lst[0] {
if char == '(' {
stack.append(char)
} else {
if stack.isEmpty {
return "No"
}
stack.pop()
}
}
if stack.isEmpty {
return "Yes"
} else {
return "No"
}
}
```

You are given an array of two strings, both strings consist of open
parentheses '(' or close parentheses ')' only.
Your job is to check if it is possible to concatenate the two strings in
some order, that the resulting string will be good.
A string S is considered to be good if and only if all parentheses in S

You are given an array of two strings, both strings consist of open
parentheses '(' or close parentheses ')' only.
Your job is to check if it is possible to concatenate the two strings in
some order, that the resulting string will be good.
A string S is considered to be good if and only if all parentheses in S
are balanced. For example: the string '(())()' is good, while the string
'())' is not.
Return 'Yes' if there's a way to make a good string, and return 'No' otherwise.

### Instruction:
Write code in Swift programming language. Don't include usage examples or tests.
You are given an array of two strings, both strings consist of open
parentheses '(' or close parentheses ')' only.
Your job is to check if it is possible to concatenate the two strings in
some order, that the resulting string will be good.
A string S is considered to be good if and only if all parentheses in S
are balanced. For example: the string '(())()' is good, while the string
'())' is not.
Return 'Yes' if there's a way to make a good string, and return 'No' otherwise.
Examples:
matchParens(lst: ["()(", ")"]) == "Yes"
matchParens(lst: [")", ")"]) == "No"
