Solution: Odd Even Linked List
Explore how to rearrange nodes in a singly linked list so all odd-indexed nodes come before even-indexed nodes while preserving order. Understand the in-place algorithm using constant extra space and linear time by managing pointers effectively.

Statement
Given the head of a singly linked list, rearrange the nodes so that all nodes at odd indexes appear first, followed by all nodes at even indexes.
The first node in the list is considered at odd index 1, the second at even index 2, and so on.
Within the odd group and the even group, the relative order of the nodes must remain the same as in the original list.
Return the head of the reordered linked list.
