1474. Delete N Nodes After M Nodes of a Linked List:

The Essence:

The question tries to teach us:

• How to traverse a Linked List.
• How to delete a node on Linked List.

Details:

• The problem-solver should need to learn how to traverse on a Linked List using a while-loop and a pointer first, on an easier example.
• It is quite easy to delete a node on Linked List, just by modifying the pointer of the predecessor node (of the current node we want to delete).
