Problem
Input to this function is a string containing multiple groups of nested parentheses. Your goal is to
separate those group into separate strings and return the array of those.
Separate groups are balanced (each open brace is properly closed) and not nested within each other
Ignore any spaces in the input string.

This function uses a stack to keep track of the opening parentheses and separates the groups when a closing parenthesis is encountered. It skips over spaces and checks if the parentheses are balanced.

# 2. **Balanced Parentheses Checker**
Given a string containing multiple groups of nested parentheses, this function checks if each group is balanced. A group is considered balanced if it starts with an opening parenthesis '(' and ends with a closing parenthesis ')', with zero or more groups inside it, which are also balanced.
The function returns `true` if all groups are balanced, otherwise it returns `false`.
Example:
```swift
// Input to this function is a string containing multiple groups of nested parentheses. Your goal is to
// separate those group into separate strings and return the array of those.
// Separate groups are balanced (each open brace is properly closed) and not nested within each other
// Ignore any spaces in the input string.
// separateParenGroups(parenString: "( ) (( )) (( )( ))") == ["()", "(())", "(()())"]
func separateParenGroups(parenString: String) -> [String] {
// Your code here
}
// Example usage:
let exampleInput = "( ) (( )) (( )( ))"
let separatedGroups = separateParenGroups(parenString: exampleInput)
print(separatedGroups) // Output: ["()", "(())", "(()())"]
```

This function uses a stack to keep track of the groups of parentheses. It iterates over the string, ignoring spaces, and for each open parenthesis, it pushes an empty string onto the stack. For each closing parenthesis, it pops the stack and appends the parentheses to the string at the top of the stack. This ensures that each group is separated into a separate string. // XCTAssertTrue failedfunc separateParenGroups(parenString: String) -> [String] {

This function uses a stack-like approach to separate the groups of parentheses. It iterates over the characters of the input string and maintains a count of open parentheses. When an open parenthesis is encountered, it is added to the current group. When a close parenthesis is encountered, it is added to the current group and the count is decremented. If the count goes negative, the parentheses are not balanced and the function returns an empty array. If the count reaches zero, it means a group is complete and is added to the result array.

Input to this function is a string containing multiple groups of nested parentheses. Your goal is to
separate those group into separate strings and return the array of those.
Separate groups are balanced (each open brace is properly closed) and not nested within each other
Ignore any spaces in the input string.

Write code in Swift programming language. Don't include usage examples or tests.
Input to this function is a string containing multiple groups of nested parentheses. Your goal is to
separate those group into separate strings and return the array of those.
Separate groups are balanced (each open brace is properly closed) and not nested within each other
Ignore any spaces in the input string.

Input to this function is a string containing multiple groups of nested parentheses. Your goal is to
separate those group into separate strings and return the array of those.
Separate groups are balanced (each open brace is properly closed) and not nested within each other
Ignore any spaces in the input string.

This function uses a stack to keep track of the nested parentheses. It iterates over each character in the input string. If the character is a space, it ignores it and continues to the next character. If the character is an opening parenthesis, it adds it to the stack and to the current group. If the character is a closing parenthesis, it removes the last opening parenthesis from the stack and adds the closing parenthesis to the current group. If the stack is empty after removing the opening parenthesis, it means that a group has been completed, so it adds the current group to the result and resets the current group. Finally, it returns the result. // XCTAssertTrue failedfunc separateParenGroups(parenString: String) -> [String] {

This function works by using a stack to keep track of the nested parentheses. It iterates over each character in the input string, ignoring any spaces. When it encounters an opening parenthesis, it adds it to the stack and to the current group string (unless the stack is empty, in which case it's the start of a new group). When it encounters a closing parenthesis, it removes the last opening parenthesis from the stack and adds the closing parenthesis to the current group string. If the stack is now empty, it adds the current group to the result array and resets the current group string. Finally, it returns the result array. // XCTAssertTrue failedfunc separateParenGroups(parenString: String) -> [String] {

### Complexity:

Space complexity: O(n) where n is the length of the input string
### Test Cases:
```swift
print(separateParenGroups(parenString: "()")) // ["()"]
print(separateParenGroups(parenString: "(()))")) // ["(())"]
print(separateParenGroups(parenString: "((()))")) // ["(()())"]
print(separateParenGroups(parenString: "(((())))")) // ["(((())))"]
print(separateParenGroups(parenString: "(((())))(((())))")) // ["(((())))", "(((())))"]
print(separateParenGroups(parenString: "(((())))(((())))(((())))")) // ["(((())))", "(((())))", "(((())))"]
```
### Conclusion:
This problem can be solved using a stack data structure. The basic idea is to iterate through the input string and keep track of the number of open parentheses. When an open parenthesis is encountered, push it onto the stack. When a closed parenthesis is encountered, pop the top element from the stack and append it to the current group. If the stack is empty when a closed parenthesis is encountered, it means that the parentheses are not balanced and the input string is invalid.currentGroup += character // cannot convert value of type 'Character' to expected argument type 'String'currentGroup += character // cannot convert value of type 'Character' to expected argument type 'String'currentGroup += character // cannot convert value of type 'Character' to expected argument type 'String'func separateParenGroups(parenString: String) -> [String] {

### Space Complexity:
O(n) where n is the length of the input string
### Notes:
This solution uses a stack data structure to keep track of the open parentheses. It iterates through the input string character by character, adding open parentheses to the stack and removing them from the stack when they are closed. At the end, the stack is empty, so all the remaining parentheses are grouped together and added to the result array.} else if character == ")" &&!stack.isEmpty { // expected '{' after 'if' conditionwhile!stack.isEmpty { // expected expression, var, or let in 'while' conditionfunc separateParenGroups(parenString: String) -> [String] {

Write code in Swift programming language. Don't include usage examples or tests.
Input to this function is a string containing multiple groups of nested parentheses. Your goal is to
separate those group into separate strings and return the array of those.
Separate groups are balanced (each open brace is properly closed) and not nested within each other
Ignore any spaces in the input string.

### Response:
```swift
func separateParenGroups(parenString: String) -> [String] {
var result = [String]()
var stack = [Character]()
for character in parenString {
if character == "(" {
stack.append(character)
} else if character == ")" {

}
}

}
return result
}
```
### Explanation:
This function first initializes an empty array `result` to store the separated groups. It also initializes an empty stack `stack` to keep track of the nested parentheses.
The function then iterates through each character in the input string `parenString`. If the current character is an opening parenthesis `(`, it is added to the stack. If the current character is a closing parenthesis `)`, it is checked to see if the stack is empty. If it is, the current character is added to the `result` array as it is not balanced. If the stack is not empty, the last opening parenthesis is removed from the stack.
After the loop completes, any remaining opening parentheses are added to the `result` array as they are not balanced. Finally, the contents of the stack are added to the `result` array as they are not balanced.
The resulting `result` array contains the separated groups of nested parentheses.while!stack.isEmpty { // expected expression, var, or let in 'while' conditionfunc separateParenGroups(parenString: String) -> [String] {
