Solution: Reorder List
Explore how to reorder a singly linked list in place without modifying node values. Understand the use of fast and slow pointers to find the middle, reverse the second half, and merge both halves. This lesson teaches an optimized approach to rearranging linked lists with linear time complexity and constant space.
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:
