Swap Nodes in Pairs
Understand how to swap every two adjacent nodes in a singly linked list without modifying node values. This lesson helps you implement an in-place solution that runs in linear time and constant space. Practice efficient linked list manipulation techniques that are essential for coding interviews and improve your algorithmic skills.

Statement
Given a singly linked list, swap every two adjacent nodes of the linked list. After the swap, return the head of the linked list.
Note: Solve the problem without modifying the values in the list’s nodes. In other ...
