Problem

Given an array of non-negative integers, return a coswift of the given array after sorting,
you will sort the given array in ascending order if the sum( first index value, last index value) is odd,
or sort it in descending order if the sum( first index value, last index value) is even.
Note:
* don't change the given array.
Examples:
sortArray(array: [] as [Int]) == [] as [Int]
sortArray(array: [5]) == [5]
sortArray(array: [2, 4, 3, 0, 1, 5]) == [0, 1, 2, 3, 4, 5]
sortArray(array: [2, 4, 3, 0, 1, 5, 6]) == [6, 5, 4, 3, 2, 1, 0]
func sortArray(array: [Int]) -> [Int] { ...
XCTAssertTrue(sortArray(array: [] as [Int]) == [] as [Int])
XCTAssertTrue(sortArray(array: [5]) == [5])
XCTAssertTrue(sortArray(array: [2, 4, 3, 0, 1, 5]) == [0, 1, 2, 3, 4, 5])
XCTAssertTrue(sortArray(array: [2, 4, 3, 0, 1, 5, 6]) == [6, 5, 4, 3, 2, 1, 0])
XCTAssertTrue(sortArray(array: [2, 1]) == [1, 2])
XCTAssertTrue(sortArray(array: [15, 42, 87, 32, 11, 0]) == [0, 11, 15, 32, 42, 87])
XCTAssertTrue(sortArray(array: [21, 14, 23, 11]) == [23, 21, 14, 11])

Given an array of non-negative integers, return a coswift of the given array after sorting,
you will sort the given array in ascending order if the sum( first index value, last index value) is odd,
or sort it in descending order if the sum( first index value, last index value) is even.
Note:
* don't change the given array.
Examples:
sortArray(array: [] as [Int]) == [] as [Int]
sortArray(array: [5]) == [5]
sortArray(array: [2, 4, 3, 0, 1, 5]) == [0, 1, 2, 3, 4, 5]
sortArray(array: [2, 4, 3, 0, 1, 5, 6]) == [6, 5, 4, 3, 2, 1, 0]<end_of_turn>

Question:
Write code in Swift programming language. Don't include usage examples or tests.
Given an array of non-negative integers, return a coswift of the given array after sorting,
you will sort the given array in ascending order if the sum( first index value, last index value) is odd,
or sort it in descending order if the sum( first index value, last index value) is even.
Note:
* don't change the given array.
Examples:
sortArray(array: [] as [Int]) == [] as [Int]
sortArray(array: [5]) == [5]
sortArray(array: [2, 4, 3, 0, 1, 5]) == [0, 1, 2, 3, 4, 5]
sortArray(array: [2, 4, 3, 0, 1, 5, 6]) == [6, 5, 4, 3, 2, 1, 0]

Answer:
```swift
func sortArray(array: [Int]) -> [Int] {
    let first = array.first!
    let last = array.last!
    let sum = first + last
    let isOdd = sum % 2 == 1
    return isOdd? array.sorted() : array.sorted(by: >)
}
```
return isOdd? array.sorted() : array.sorted(by: >) // expected expression
return isOdd? array.sorted() : array.sorted(by: >) // consecutive statements on a line must be separated by ';'
return isOdd? array.sorted() : array.sorted(by: >) // cannot use optional chaining on non-optional value of type 'Bool'
return isOdd? array.sorted() : array.sorted(by: >) // result of call to 'sorted()' is unused
return isOdd? array.sorted() : array.sorted(by: >) // consecutive statements on a line must be separated by ';'

func sortArray(array: [Int]) -> [Int] {
    let sum = array.reduce(0, +)
    let isOdd = sum % 2 == 1
    return isOdd? array.sorted() : array.sorted(by: >)

Question:
Write code in Swift programming language. Don't include usage examples or tests.
Given an array of non-negative integers, return a coswift of the given array after sorting,
you will sort the given array in ascending order if the sum( first index value, last index value) is odd,
or sort it in descending order if the sum( first index value, last index value) is even.

or sort it in descending order if the sum( first index value, last index value) is even.
Note:
* don't change the given array.
Examples:
sortArray(array: [] as [Int]) == [] as [Int]
sortArray(array: [5]) == [5]
sortArray(array: [2, 4, 3, 0, 1, 5]) == [0, 1, 2, 3, 4, 5]
sortArray(array: [2, 4, 3, 0, 1, 5, 6]) == [6, 5, 4, 3, 2, 1, 0]
### Response:
```swift
func sortArray(array: [Int]) -> [Int] {
    var array = array
    if array.count > 1 {
        if array.first! + array.last! % 2 == 0 {

you will sort the given array in ascending order if the sum( first index value, last index value) is odd,
or sort it in descending order if the sum( first index value, last index value) is even.
Note:
* don't change the given array.
Examples:
sortArray(array: [] as [Int]) == [] as [Int]
sortArray(array: [5]) == [5]
sortArray(array: [2, 4, 3, 0, 1, 5]) == [0, 1, 2, 3, 4, 5]
sortArray(array: [2, 4, 3, 0, 1, 5, 6]) == [6, 5, 4, 3, 2, 1, 0]
### Response:
```swift
func sortArray(array: [Int]) -> [Int] {
    let sum = array.first! + array.last!
    if sum % 2 == 0 {
        return array.sorted(by: >)
    } else {
        return array.sorted(by: <)
    }
}

This function takes an array of non-negative integers and sorts the given array in ascending order if the sum of the first and last elements is ODD, or sorts it in descending order if the sum of the first and last elements is EVEN.

The function first calculates the sum of the first and last elements of the given array. If the sum is EVEN, it sorts the array in descending order using the sorted(by: >) method. If the sum is ODD, it sorts the array in ascending order using the sorted() method.

The function then returns the sorted array.

Given an array of non-negative integers, return a coswift of the given array after sorting,
you will sort the given array in ascending order if the sum( first index value, last index value) is odd,
or sort it in descending order if the sum( first index value, last index value) is even.

Question:
Write code in Swift programming language. Don't include usage examples or tests.
Given an array of non-negative integers, return a coswift of the given array after sorting,
you will sort the given array in ascending order if the sum( first index value, last index value) is odd,
or sort it in descending order if the sum( first index value, last index value) is even.
Note:
* don't change the given array.
Examples:
sortArray(array: [] as [Int]) == [] as [Int]
sortArray(array: [5]) == [5]
sortArray(array: [2, 4, 3, 0, 1, 5]) == [0, 1, 2, 3, 4, 5]

Given an array of non-negative integers, return a coswift of the given array after sorting,
you will sort the given array in ascending order if the sum( first index value, last index value) is odd,
or sort it in descending order if the sum( first index value, last index value) is even.
Note:
* don't change the given array.
Examples:
sortArray(array: [] as [Int]) == [] as [Int]
sortArray(array: [5]) == [5]
sortArray(array: [2, 4, 3, 0, 1, 5]) == [0, 1, 2, 3, 4, 5]
sortArray(array: [2, 4, 3, 0, 1, 5, 6]) == [6, 5, 4, 3, 2, 1, 0]

Question:
Write code in Swift programming language. Don't include usage examples or tests.
Given an array of non-negative integers, return a coswift of the given array after sorting,
you will sort the given array in ascending order if the sum( first index value, last index value) is odd,
or sort it in descending order if the sum( first index value, last index value) is even.
Note:
* don't change the given array.
Examples:
sortArray(array: [] as [Int]) == [] as [Int]
sortArray(array: [5]) == [5]
sortArray(array: [2, 4, 3, 0, 1, 5]) == [0, 1, 2, 3, 4, 5]

Question:
Write code in Swift programming language. Don't include usage examples or tests.
Given an array of non-negative integers, return a coswift of the given array after sorting,
you will sort the given array in ascending order if the sum( first index value, last index value) is odd,
or sort it in descending order if the sum( first index value, last index value) is even.
Note:
* don't change the given array.
Examples:
sortArray(array: [] as [Int]) == [] as [Int]
sortArray(array: [5]) == [5]
sortArray(array: [2, 4, 3, 0, 1, 5]) == [0, 1, 2, 3, 4, 5]
sortArray(array: [2, 4, 3, 0, 1, 5, 6]) == [6, 5, 4, 3, 2, 1, 0]

Answer:
```swift
func sortArray(array: [Int]) -> [Int] {
    let sum = array.first! + array.last!
    if sum % 2 == 0 {
        return array.sorted(by: >)
    } else {
        return array.sorted()
    }
}

Given an array of non-negative integers, return a coswift of the given array after sorting,
you will sort the given array in ascending order if the sum( first index value, last index value) is odd,
or sort it in descending order if the sum( first index value, last index value) is even.
Note:
* don't change the given array.
Examples:
sortArray(array: [] as [Int]) == [] as [Int]
sortArray(array: [5]) == [5]
sortArray(array: [2, 4, 3, 0, 1, 5]) == [0, 1, 2, 3, 4, 5]
sortArray(array: [2, 4, 3, 0, 1, 5, 6]) == [6, 5, 4, 3, 2, 1, 0]

### Instruction:
Write code in Swift programming language. Don't include usage examples or tests.
Given an array of non-negative integers, return a coswift of the given array after sorting,
you will sort the given array in ascending order if the sum( first index value, last index value) is odd,
or sort it in descending order if the sum( first index value, last index value) is even.
Note:
* don't change the given array.
Examples:
sortArray(array: [] as [Int]) == [] as [Int]
sortArray(array: [5]) == [5]

```
### Explanation:
The function `sortArray` takes an array of integers as input and returns a new sorted array.
The function first creates a copy of the input array `sortedArray` and then sorts it using the `sort` method of the array.
The `sort` method sorts the array in ascending order if the sum( first index value, last index value) is odd,
or sorts it in descending order if the sum( first index value, last index value) is even.
The function then returns the sorted array.

### Test Cases:
```swift
print(sortArray(array: [] as [Int])) // []
print(sortArray(array: [5])) // [5]
print(sortArray(array: [2, 4, 3, 0, 1, 5])) // [0, 1, 2, 3, 4, 5]
print(sortArray(array: [2, 4, 3, 0, 1, 5, 6])) // [6, 5, 4, 3, 2, 1, 0]
```
### Complexity:
The time complexity of the `sortArray` function is O(n log n) because the `sort` method of the array sorts the array in place and takes O(n log n) time.
The space complexity of the `sortArray` function is O(n) because the function creates a new array of size n and sorts it in place.

Given an array of non-negative integers, return a coswift of the given array after sorting,
you will sort the given array in ascending order if the sum( first index value, last index value) is odd,
or sort it in descending order if the sum( first index value, last index value) is even.
Note:

Write code in Swift programming language. Don't include usage examples or tests.
Given an array of non-negative integers, return a coswift of the given array after sorting,
you will sort the given array in ascending order if the sum( first index value, last index value) is odd,
or sort it in descending order if the sum( first index value, last index value) is even.
Note:
* don't change the given array.
