Solution: Reorder List
Explore how to reorder a singly linked list in place by identifying the middle node with two pointers, reversing the second half, and merging the halves alternately. This lesson helps you understand efficient linked list manipulation techniques with O(n) time and O(1) space complexity, mastering memory-optimized operations in 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:
