This problem is about reversing a linked list. Given a linked list, the goal is to reverse the order of the nodes in the list. For example, if the input list is 1 -> 2 -> 3 -> 4 -> 5, the output should be 5 -> 4 -> 3 -> 2 -> 1.

#### Problem

```Given a linked list, reverse the order of the nodes in the list.
For example, given the following list:
1 -> 2 -> 3 -> 4 -> 5
The output should be:
5 -> 4 -> 3 -> 2 -> 1
Input:
1 -> 2 -> 3 -> 4 -> 5
Output:
5 -> 4 -> 3 -> 2 -> 1```

#### Solution

This solution is in JavaScript. Our A.I. can create solutions in multiple languages.
```// Solution:
// The optimal solution is to use a stack to store the nodes in reverse order.
// Then, we can pop the nodes off the stack and add them to the end of the list.
// This solution is optimal because it only requires one pass through the list.
// It also only requires O(n) space, where n is the number of nodes in the list.

// Example:
// Input: 1 -> 2 -> 3 -> 4 -> 5
// Output: 5 -> 4 -> 3 -> 2 -> 1

// Time Complexity: O(n)
// Space Complexity: O(n)

const stack = [];

while (current) {
stack.push(current);
current = current.next;
}

while (stack.length) {
current.next = stack.pop();
current = current.next;
}

current.next = null;
