Grokking the Coding Interview Patterns in Python

Delete N Nodes After M Nodes of a Linked List

Explore how to modify a linked list in place by deleting n nodes after traversing m nodes repeatedly until the end. Understand this efficient technique to handle linked list manipulations without extra memory allocation, enhancing your problem-solving skills in coding interviews.

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.
