Reverse Nodes in Even Length Groups
Understand how to reverse nodes in each group of a linked list when the group has an even number of nodes. This lesson covers assigning nodes to sequential groups, detecting even-length groups, and applying in-place reversal to modify the linked list efficiently.

Statement
Given the head of a linked list, the nodes in it are assigned to each group in a sequential manner. The length of these groups follows the sequence ...
