Reorder List

Explore how to reorder a singly linked list by rearranging node links without altering node values. Learn efficient in-place manipulation techniques for node reordering by understanding the pattern of folding the list to interleave nodes from start and end. Practice coding this common linked list pattern in a hands-on environment to strengthen your problem-solving approach for coding interviews.

Statement

Given the head of a singly linked list, reorder the list as if it were folded on itself. For example, if the list is represented as follows:
