Delete N Nodes After M Nodes of a Linked List

Understand how to manipulate a linked list by deleting N nodes after skipping M nodes in an efficient, in-place manner. Explore traversal and deletion strategies that help you implement this common linked list pattern, preparing you for coding interview challenges.

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 n nodes and delete them.

  4. Repeat steps 2 and 3 above until the end of the linked list is reached.

Constraints:

  • 1≤1 \leq ...
