Is it possible to use a Stack to reverse a linked list?

Definitely! You can push all the nodes onto the stack and then pop them off, which will give you the linked list in the reversed order. Just keep in mind that while popping, you'll need to adjust the pointer to the next node each time to maintain the linked structure.

Just remember how stacks work: the first one in is the last one out. So you're reversing the order as you pop them off. Just be cautious about how you manage the pointers!

I've actually tried this on paper before asking, and it seems straightforward! You just need to load everything into the stack and pop it out—that’s O(n) time complexity.

While using a stack to reverse a linked list is totally doable, it's not the most efficient. It involves unnecessary copying of data and requires extra space. If you have access to modify the list, a recursive approach can reverse it without additional storage, just rearranging the nodes instead.
