In this video, we learn how to reverse nodes in groups of k inside a linked list — a very popular and frequently asked interview problem. The goal is to reverse every consecutive block of k nodes while keeping the overall structure of the list intact. What this video covers How to identify groups of k nodes before attempting reversal Why partial groups (less than k nodes remaining) should stay as they are Step-by-step pointer manipulation to reverse each group in-place How to correctly reconnect the reversed segments back into the main linked list A clean and structured explanation of how the pointers move during each reversal Time complexity: O(n) Space complexity: O(1) Why this matters This is one of the most important linked list patterns used in many advanced problems. Mastering k-group reversal improves your understanding of pointer manipulation, segment-based operations, and linked list restructuring — all key interview skills.
