REVERSE NODES IN K GROUP | LEETCODE 25 | PYTHON SOLUTION

Discord Community:   / discord   Problem Link: https://leetcode.com/problems/reverse... In today's video we will be solving a quite tricky linked list question: Reverse Nodes in K Group (Leetcode # 25). This question looks quite easy when you are approaching it on paper but actually solving this in the O(1) space required is quite difficult. There's quite a few pointer variables you need to maintain in order to correctly re-link the list after a K group reversal. In the end it isn't too bad but it might take some time to wrap your head around how and why we maintain some of the key variables here.
