Swap Nodes in Pairs
Understand how to swap every two adjacent nodes in a singly linked list by manipulating the nodes themselves without altering their values. This lesson helps you implement an efficient O(n) time and O(1) space solution to perform in-place node swaps, strengthening your skills in linked list manipulation for coding interviews.
