Solution: Reorder List
Explore how to reorder a singly linked list by folding it onto itself using in-place techniques. Learn to find the middle node efficiently with two pointers, reverse the second half of the list, and merge the halves alternately. This lesson helps you implement a linear time solution with constant space complexity for reordering linked lists without modifying node values.
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:
...
