Problem
Create a function that returns a tuple (a, b), where 'a' is
the largest of negative integers, and 'b' is the smallest
of positive integers in an array.
If there is no negative or positive integers, return them as nil.
Examples:
largestSmallestIntegers(lst: [2, 4, 1, 3, 5, 7]) == (nil, 1)
largestSmallestIntegers(lst: [] as [Int]) == (nil, nil)

Write code in Swift programming language. Don't include usage examples or tests.
Create a function that returns a tuple (a, b), where 'a' is
the largest of negative integers, and 'b' is the smallest
of positive integers in an array.
If there is no negative or positive integers, return them as nil.
Examples:

largestSmallestIntegers(lst: [] as [Int]) == (nil, nil)

Write code in Swift programming language. Don't include usage examples or tests.
Create a function that returns a tuple (a, b), where 'a' is
the largest of negative integers, and 'b' is the smallest
of positive integers in an array.
If there is no negative or positive integers, return them as nil.
Examples:
largestSmallestIntegers(lst: [2, 4, 1, 3, 5, 7]) == (nil, 1)
largestSmallestIntegers(lst: [] as [Int]) == (nil, nil)

Write code in Swift programming language. Don't include usage examples or tests.
Create a function that returns a tuple (a, b), where 'a' is
the largest of negative integers, and 'b' is the smallest
of positive integers in an array.
If there is no negative or positive integers, return them as nil.
Examples:

Create a function that returns a tuple (a, b), where 'a' is
the largest of negative integers, and 'b' is the smallest
of positive integers in an array.
If there is no negative or positive integers, return them as nil.
Examples:
largestSmallestIntegers(lst: [2, 4, 1, 3, 5, 7]) == (nil, 1)
largestSmallestIntegers(lst: [] as [Int]) == (nil, nil)
largestSmallestIntegers(lst: [0]) == (nil, nil)

}Question:
Write code in Swift programming language. Don't include usage examples or tests.
Create a function that returns a tuple (a, b), where 'a' is
the largest of negative integers, and 'b' is the smallest
of positive integers in an array.
If there is no negative or positive integers, return them as nil.
Examples:
largestSmallestIntegers(lst: [2, 4, 1, 3, 5, 7]) == (nil, 1)
largestSmallestIntegers(lst: [] as [Int]) == (nil, nil)
largestSmallestIntegers(lst: [0]) == (nil, nil)
Answer:
```swift
func largestSmallestIntegers(lst: [Int]) -> (Int?, Int?) {
var negative: Int?
var positive: Int?
for num in lst {
if num < 0 {
if negative == nil || num > negative! {
negative = num
}
} else if num > 0 {
if positive == nil || num < positive! {
positive = num
}
}
}
return (negative, positive)
}
```func largestSmallestIntegers(lst: [Int]) -> (Int?, Int?) {
var largestNegative: Int? = nil
var smallestPositive: Int? = nil
for num in lst {
if num < 0 && (largestNegative == nil || num > largestNegative!) {
largestNegative = num
} else if num > 0 && (smallestPositive == nil || num < smallestPositive!) {
smallestPositive = num
}
}
return (largestNegative, smallestPositive)

of positive integers in an array.
If there is no negative or positive integers, return them as nil.
Examples:
largestSmallestIntegers(lst: [2, 4, 1, 3, 5, 7]) == (nil, 1)
largestSmallestIntegers(lst: [] as [Int]) == (nil, nil)
largestSmallestIntegers(lst: [0]) == (nil, nil)

}Question:
Write code in Swift programming language. Don't include usage examples or tests.
Create a function that returns a tuple (a, b), where 'a' is
the largest of negative integers, and 'b' is the smallest
of positive integers in an array.
If there is no negative or positive integers, return them as nil.
Examples:
largestSmallestIntegers(lst: [2, 4, 1, 3, 5, 7]) == (nil, 1)
largestSmallestIntegers(lst: [] as [Int]) == (nil, nil)
largestSmallestIntegers(lst: [0]) == (nil, nil)

### Instruction:
Write code in Swift programming language. Don't include usage examples or tests.
Create a function that returns a tuple (a, b), where 'a' is
the largest of negative integers, and 'b' is the smallest
of positive integers in an array.
If there is no negative or positive integers, return them as nil.
Examples:
largestSmallestIntegers(lst: [2, 4, 1, 3, 5, 7]) == (nil, 1)
largestSmallestIntegers(lst: [] as [Int]) == (nil, nil)
largestSmallestIntegers(lst: [0]) == (nil, nil)

Write code in Swift programming language. Don't include usage examples or tests.
Create a function that returns a tuple (a, b), where 'a' is
the largest of negative integers, and 'b' is the smallest
of positive integers in an array.
If there is no negative or positive integers, return them as nil.
Examples:
largestSmallestIntegers(lst: [2, 4, 1, 3, 5, 7]) == (nil, 1)
largestSmallestIntegers(lst: [] as [Int]) == (nil, nil)

}### Instruction:
Write code in Swift programming language. Don't include usage examples or tests.
Create a function that returns a tuple (a, b), where 'a' is
the largest of negative integers, and 'b' is the smallest
of positive integers in an array.
If there is no negative or positive integers, return them as nil.
Examples:
largestSmallestIntegers(lst: [2, 4, 1, 3, 5, 7]) == (nil, 1)
largestSmallestIntegers(lst: [] as [Int]) == (nil, nil)
largestSmallestIntegers(lst: [0]) == (nil, nil)
### Response:
```swift

for i in lst {
if i < 0 {
if largestNegative == nil {
largestNegative = i
} else if i > largestNegative {

} else if i > 0 {
if smallestPositive == nil {
smallestPositive = i
} else if i < smallestPositive {
smallestPositive = i
}
}
}

Explanation:
* We iterate through the array `lst` using a for loop.
* For each integer `num`, we check if it is positive or negative.
* If `num` is positive, we check if `smallest` is `nil`. If it is, we set `smallest` to `num`. If `num` is less than `smallest`, we set `smallest` to `num`.
* If `num` is negative, we check if `largest` is `nil`. If it is, we set `largest` to `num`. If `num` is greater than `largest`, we set `largest` to `num`.
* After the loop, we return the tuple `(largest, smallest)`.
* If the array is empty or contains only one element, we return `(nil, nil)`.
* If the array contains only zero, we return `(nil, nil)`.func largestSmallestIntegers(lst: [Int]) -> (Int?, Int?) {

Explanation:
* The function takes an array of integers as an argument.
* It initializes two variables, largest and smallest, to nil.
* It then loops through each integer in the array.
* If the integer is positive, it checks if the smallest variable is nil. If it is, it sets the smallest variable to the current integer. If it is not, it checks if the current integer is less than the value of the smallest variable. If it is, it updates the smallest variable to the current integer.
* If the integer is negative, it checks if the largest variable is nil. If it is, it sets the largest variable to the current integer. If it is not, it checks if the current integer is greater than the value of the largest variable. If it is, it updates the largest variable to the current integer.
* Finally, the function returns a tuple containing the value of the largest variable and the value of the smallest variable. If both variables are nil, it returns (nil, nil).
Note: This solution assumes that the input array will not contain any negative or positive integers that are equal to each other. If this is not the case, the solution may need to be modified.

Write code in Swift programming language. Don't include usage examples or tests.
Create a function that returns a tuple (a, b), where 'a' is
the largest of negative integers, and 'b' is the smallest
of positive integers in an array.
If there is no negative or positive integers, return them as nil.

largestSmallestIntegers(lst: [2, 4, 1, 3, 5, 7]) == (nil, 1)
largestSmallestIntegers(lst: [] as [Int]) == (nil, nil)
largestSmallestIntegers(lst: [0]) == (nil, nil)
### Response:
```swift

if largestNegative == nil || num > largestNegative! {
largestNegative = num
}
} else if num > 0 {
if smallestPositive == nil || num < smallestPositive! {
smallestPositive = num

return (largestNegative, smallestPositive)

Write code in Swift programming language. Don't include usage examples or tests.
Create a function that returns a tuple (a, b), where 'a' is
the largest of negative integers, and 'b' is the smallest
of positive integers in an array.
If there is no negative or positive integers, return them as nil.
