This function uses a stack to keep track of the opening brackets. For each character in the string, if it's an opening bracket, it's pushed onto the stack. If it's a closing bracket, the function checks if the stack is empty or if the top of the stack is not the corresponding opening bracket. If either condition is true, the brackets are not balanced and the function returns false. If the loop completes without finding any issues, the brackets are balanced and the function returns true.func correctBracketing(brackets: String) -> Bool {

This function uses a stack to keep track of the opening brackets. When a closing bracket is encountered, it checks if there is a corresponding opening bracket by popping from the stack. If the stack is empty or there are remaining opening brackets after processing the entire string, the function returns false, indicating that the brackets are not balanced.

This function uses a stack to keep track of the opening brackets. For each opening bracket "<", it pushes it onto the stack. For each closing bracket ">", it checks if the stack is empty. If it is, it means there is no corresponding opening bracket, so it returns false. Otherwise, it pops the opening bracket from the stack.

### Explanation:
This function takes a string of brackets as input and checks if every opening bracket has a corresponding closing bracket. It does this by creating an empty stack to store the opening brackets, and then iterating over the input string. For each character in the string, it checks if it is an opening bracket (i.e. "<") and appends it to the stack. If it is a closing bracket (i.e. ">"), it checks if the stack is empty. If it is not empty, it removes the last opening bracket from the stack. If the stack is empty at the end, it means that there was an unmatched closing bracket. If the string is finished, it checks if the stack is empty. If it is, it means that all opening brackets have been matched with a closing bracket, so it returns true. If it is not, it means that there was an unmatched opening bracket, so it returns false.
### Time Complexity:
The time complexity of this function is O(n), where n is the length of the input string. This is because the function iterates over the input string once, and for each character, it either appends it to the stack or removes it from the stack.
### Space Complexity:
The space complexity of this function is O(n), where n is the length of the input string. This is because the function creates an array to store the opening brackets, and for each character, it either appends it to the array or removes it from the array.func correctBracketing(brackets: String) -> Bool {
var stack = [Character]()
for character in brackets {
if character == "<" {
stack.append(character)
} else if character == ">" {
if stack.isEmpty {
return false
}
stack.removeLast()
}
}

### Notes:
This solution uses a stack data structure to keep track of the opening brackets. It iterates through the input string and pushes "<" characters onto the stack, and ">" characters remove the last element from the stack if it is not empty.

### Explanation:
This function takes a string of brackets as input and returns a boolean indicating whether the brackets are correctly bracketed.
The function initializes an empty array `stack` to store the opening brackets. It then iterates through each character in the input string `brackets`.
If the current character is "<", the function appends it to the `stack`. If the current character is ">", the function checks if the `stack` is empty. If it is, the function returns `false`, indicating that there is an unmatched closing bracket. If the `stack` is not empty, the function removes the last element from the `stack`.
After the loop completes, the function checks if the `stack` is empty. If it is, the function returns `true`, indicating that all opening brackets have been matched with a closing bracket. If the `stack` is not empty, the function returns `false`, indicating that there are unmatched opening brackets.
### Time Complexity:
The time complexity of this function is O(n), where n is the length of the input string `brackets`.
### Space Complexity:
The space complexity of this function is O(n), where n is the length of the input string `brackets`.
### Test Cases:
```swift
print(correctBracketing(brackets: "<")) // false
print(correctBracketing(brackets: "<>")) // true
print(correctBracketing(brackets: "<<><>>")) // true
print(correctBracketing(brackets: "><<>")) // false
```
### Conclusion:
This function correctly determines whether a string of brackets is correctly bracketed. It uses a stack data structure to keep track of the opening brackets, and it returns `true` if all opening brackets have a corresponding closing bracket, and `false` otherwise. The time and space complexity of the function are both O(n), which is optimal.func correctBracketing(brackets: String) -> Bool {
var stack = [Character]()
for character in brackets {
if character == "<" {
stack.append(character)

stack.removeLast()
}
}
return stack.isEmpty

}

```
### Explanation:
This function takes a string of brackets as input and returns a boolean indicating whether the brackets are correctly bracketed. It does this by first creating an empty array `stack` to store the opening brackets. Then, it iterates through each character in the input string. If the character is "<", it is added to the stack. If the character is ">", it is checked to see if the stack is empty. If it is, then the brackets are not correctly bracketed and the function returns `false`. If the stack is not empty, then the last opening bracket is removed from the stack. Finally, if the stack is empty, then the brackets are correctly bracketed and the function returns `true`.
### Time Complexity:
The time complexity of this function is O(n), where n is the length of the input string. This is because the function iterates through each character in the input string and performs a constant number of operations on the stack.
### Space Complexity:
The space complexity of this function is O(n), where n is the length of the input string. This is because the function creates an array to store the opening brackets and the stack.func correctBracketing(brackets: String) -> Bool {
var stack: [Character] = []
