Solution: Delete N Nodes After M Nodes of a Linked List

Explore how to manipulate a linked list in place by deleting N nodes after retaining M nodes repeatedly. This lesson teaches you to traverse the list efficiently, update pointers to remove specified nodes, and maintain correct connections, enabling you to solve linked list deletion problems with optimal time and space performance.

We'll cover the following...

Statement

Given the head of a linked list and two integers, m and n, remove some specific nodes from the list and return the head of the modified, linked list. The list should be traversed, and nodes removed as follows:

  1. Start with the head node and set it as the current node.

  2. Traverse the next m nodes from the current node without deleting them.

  3. Traverse the next ...
