Solution: Reorder List
Explore how to reorder a singly linked list in-place by mastering three key steps: locating the middle node using two pointers, reversing the second half of the list, and merging the two halves alternately. This lesson guides you to implement an efficient O(n) time and O(1) space complexity solution that updates node links without altering 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:
