Problem
Create a function which returns the largest index of an element which
is not greater than or equal to the element immediately preceding it. If
no such element exists then return -1. The given array will not contain
duplicate values.

canArrange(arr: [1, 2, 4, 3, 5]) == 3

Write code in Swift programming language. Don't include usage examples or tests.
Create a function which returns the largest index of an element which
is not greater than or equal to the element immediately preceding it. If
no such element exists then return -1. The given array will not contain
duplicate values.
Examples:

This function uses a stack to keep track of the indices of elements that are not greater than or equal to the element immediately preceding them. It iterates over the array and checks if the current element is greater than or equal to the element at the top of the stack. If it is, it pops the stack and pushes the current index. This ensures that the stack always contains indices of elements that are not greater than or equal to the element immediately preceding them.
The function then iterates over the stack and returns the largest index found. If no such index exists, it returns -1.
The time complexity of this solution is O(n), where n is the number of elements in the array.} // missing return in global function expected to return 'Int'func canArrange(arr: [Int]) -> Int {

This function uses a stack to keep track of the indices of elements that are not greater than or equal to the element immediately preceding them. It iterates over the array and checks if the current element is greater than or equal to the element at the index stored in the stack. If it is, it pops the index from the stack and pushes the current index onto the stack. This ensures that the stack always contains indices of elements that are not greater than or equal to the element immediately preceding them.
The function then iterates over the stack to find the largest index that is not greater than or equal to the element immediately preceding it. If such an index is found, it returns the index of the element that is not greater than or equal to the element immediately preceding it. If no such index is found, it returns -1.} // missing return in global function expected to return 'Int'func canArrange(arr: [Int]) -> Int {

This function uses a stack to keep track of the elements that are not greater than or equal to the element immediately preceding it. It iterates over the array from the second element to the last, comparing each element with the element at the index before it. If an element is not greater than or equal to the element before it, it is pushed onto the stack. If it is greater than or equal, it pops the stack until it finds an element that is greater than or equal to it. If no such element is found, it returns -1.
The time complexity of this approach is O(n), where n is the length of the array, as each element is processed once.} // missing return in global function expected to return 'Int'func canArrange(arr: [Int]) -> Int {

This function uses a stack to keep track of the indices of elements that are not greater than or equal to the element immediately preceding them. It iterates over the array and checks if the current element is greater than or equal to the element at the top of the stack. If it is, it pops the stack and pushes the current index onto it. This ensures that the stack always contains indices of elements that are not greater than or equal to the elements preceding them.
The function then iterates over the stack and returns the largest index found. If no such index exists, it returns -1.
The time complexity of this solution is O(n), where n is the length of the array, as it requires a single pass to build the stack and another pass to find the largest index. The space complexity is O(n) as it requires additional space to store the stack.} // missing return in global function expected to return 'Int'func canArrange(arr: [Int]) -> Int {

Write code in Swift programming language. Don't include usage examples or tests.
Create a function which returns the largest index of an element which
is not greater than or equal to the element immediately preceding it. If
no such element exists then return -1. The given array will not contain
duplicate values.

This solution uses a count array to keep track of the number of occurrences of each element in the input array. It then iterates over the count array, starting at index 1, and checks if the element at that index is greater than or equal to the element immediately preceding it. If it is, then the element at that index is not greater than or equal to any other element in the array, and the function returns the index of that element. If the loop completes and no such element is found, then the function returns -1. // Fatal error: Index out of rangefunc canArrange(arr: [Int]) -> Int {

Explanation:
The function first creates an array `count` to keep track of the number of occurrences of each digit in the input array. It does this by dividing each element of the input array by 10 and keeping the remainder. For example, if the input array is `[1, 2, 4, 3, 5]`, the function will create an array `count` with the following values: `[0, 0, 0, 1, 0, 0, 0, 0, 0, 0]`.
The function then iterates over the `count` array and checks if each element is greater than the element immediately preceding it. If any element is found to be greater than its predecessor, the function returns -1 to indicate that no such element exists. If no such element is found, the function returns the sum of the elements in the `count` array minus the total number of occurrences of each digit in the input array.
Note that the input array will not contain duplicate values, so the function does not need to check for duplicates.
Time complexity: O(n) where n is the length of the input array.
Space complexity: O(1) since the function only uses a constant amount of memory.
### Test Cases:
```swift
print(canArrange(arr: [1, 2, 4, 3, 5])) // 3
print(canArrange(arr: [1, 2, 3])) // -1
print(canArrange(arr: [1, 2, 3, 4, 5, 6, 7, 8, 9])) // 8
```
### Conclusion:
This problem can be solved using a simple counting approach. The function first creates an array to keep track of the number of occurrences of each digit in the input array, and then iterates over the array to check if each element is greater than the element immediately preceding it. If any element is found to be greater than its predecessor, the function returns -1 to indicate that no such element exists. If no such element is found, the function returns the sum of the elements in the array minus the total number of occurrences of each digit in the input array. This solution has a time complexity of O(n) and a space complexity of O(1) since it only uses a constant amount of memory. // XCTAssertTrue failedfunc canArrange(arr: [Int]) -> Int {

It then iterates over the array and increments the count at each index by the number of elements that are less than or equal to the element immediately preceding it.

}### Instruction:
Write code in Swift programming language. Don't include usage examples or tests.
Create a function which returns the largest index of an element which
is not greater than or equal to the element immediately preceding it. If
no such element exists then return -1. The given array will not contain
duplicate values.
Examples:
canArrange(arr: [1, 2, 4, 3, 5]) == 3
canArrange(arr: [1, 2, 3]) == -1
