Finding the loop in a linked list
Use two pointers, one slow and one fast, to detect a loop
If the fast pointer catches up with the slow pointer, there is a loop
Once a loop is detected, use another pointer to find the start of the loop
Reversing a linked list involves changing the direction of its pointers to reverse the order of nodes.
Iterative approach: Use three pointers (prev, current, next) to reverse links.
Example: For list 1 -> 2 -> 3, after reversal it becomes 3 -> 2 -> 1.
Recursive approach: Reverse the rest of the list and adjust pointers.
Example: For list 4 -> 5 -> 6, recursively reverse to get 6 -> 5 -> 4.
