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

Explore how to efficiently delete N nodes after keeping M nodes in a singly linked list. This lesson guides you through an in-place traversal algorithm that retains and skips nodes in groups, reconnecting the list appropriately. Learn the step-by-step process, examine code structure, and understand the time and space complexities to master linked list manipulation.

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 ...
