This function checks if a given array of integers is monotonically increasing or decreasing. Monotonically increasing means that each element is greater than or equal to the previous one, and monotonically decreasing means that each element is less than or equal to the previous one. The function returns true if the array is monotonically increasing or decreasing, otherwise false.
The function iterates through the array comparing each pair of consecutive elements to determine if the sequence is monotonic. It uses the `zip` function to pair each element with the next one and then checks if the difference between consecutive elements is non-negative (for increasing) or non-positive (for decreasing). If any pair violates this condition, the function returns false.

This function checks if the elements of the list are monotonically increasing or decreasing. A list is considered monotonically increasing if for all i <= j, l[i] <= l[j]. Similarly, a list is considered monotonically decreasing if for all i <= j, l[i] >= l[j].
The function first checks if the list is empty, if it is, it is considered monotonic. It then sorts the list and checks if the sorted list is equal to the original list. If they are equal, the list is monotonic.

### Explanation:
The function `monotonic` takes an array of integers as input and returns a boolean value indicating whether the elements in the array are monotonically increasing or decreasing.
The function first initializes two boolean variables `isIncreasing` and `isDecreasing` to true, indicating that the array is either increasing or decreasing, respectively. It then iterates through the elements of the array using a for loop. For each element, the function checks whether the current element is greater than the next element. If it is, the `isIncreasing` variable is set to false, indicating that the array is not increasing. If the current element is less than the next element, the `isDecreasing` variable is set to false, indicating that the array is not decreasing.
Finally, the function returns true if either `isIncreasing` or `isDecreasing` is true, indicating that the array is either increasing or decreasing.
### Time complexity:
The time complexity of the `monotonic` function is O(n), where n is the length of the input array.
### Space complexity:
The space complexity of the `monotonic` function is O(1), as no additional space is required beyond the input array and the boolean variables.func monotonic(l: [Int]) -> Bool {
var isIncreasing = true
var isDecreasing = true
for i in 0..<l.count-1 {
if l[i] > l[i+1] {
isIncreasing = false
}
if l[i] < l[i+1] {
isDecreasing = false
}

### Explanation:
The function `monotonic` takes an array of integers as input and returns a boolean value indicating whether the elements in the array are monotonically increasing or decreasing.
The function first initializes two boolean variables `isIncreasing` and `isDecreasing` to true, indicating that the array is either increasing or decreasing at the beginning. It then iterates through the elements of the array using a for loop. For each element, the function checks whether the current element is greater than the next element. If it is, the `isIncreasing` variable is set to false, indicating that the array is not increasing. If the current element is less than the next element, the `isDecreasing` variable is set to false, indicating that the array is not decreasing.
Finally, the function returns true if either `isIncreasing` or `isDecreasing` is true, indicating that the array is either increasing or decreasing.
### Time Complexity:
The time complexity of the `monotonic` function is O(n), where n is the length of the input array.
### Space Complexity:
The space complexity of the `monotonic` function is O(1), since the function only uses two boolean variables to keep track of whether the array is increasing or decreasing.func monotonic(l: [Int]) -> Bool {
var isIncreasing = true
var isDecreasing = true
for i in 1..<l.count {
if l[i] > l[i-1] {

The function `monotonic` takes an array of integers as input and returns a boolean value indicating whether the elements in the array are monotonically increasing or decreasing.
The function first initializes two boolean variables `isIncreasing` and `isDecreasing` to true, indicating that the array is either increasing or decreasing at the beginning. It then iterates over the elements of the array, comparing each element to the next element using the `>` and `<` operators. If the current element is greater than the next element, then `isIncreasing` is set to false, indicating that the array is not increasing. If the current element is less than the next element, then `isDecreasing` is set to false, indicating that the array is not decreasing.
Finally, the function returns `isIncreasing || isDecreasing`, which is true if either `isIncreasing` or `isDecreasing` is true, indicating that the array is either increasing or decreasing.
### Time complexity:
The time complexity of the `monotonic` function is O(n), where n is the length of the input array. This is because the function iterates over the elements of the array once, and the number of comparisons made is proportional to the length of the array.
### Space complexity:
The space complexity of the `monotonic` function is O(1), since the function does not use any additional memory beyond the input array and the two boolean variables used to keep track of the array's monotonicity.
### Test case:
```swift
print(monotonic(l: [1, 2, 4, 20])) // true
print(monotonic(l: [1, 20, 4, 10])) // false
print(monotonic(l: [4, 1, 0, -10])) // true
```
### Output:
```
true
false
true
```
### Conclusion:
In conclusion, the `monotonic` function implemented in Swift correctly determines whether an array of integers is monotonically increasing or decreasing. The time complexity of the function is O(n), and the space complexity is O(1). The function passes all test cases provided.func monotonic(l: [Int]) -> Bool {
