Welcome to my channel.
In this video, I have solved the "Find the first node of loop in linked list" problem from GFG Practice - Problem Of The Day. In gfg potd today solution, I have used the two-pointer approach to detect a loop in the linked list in java. This problem has been asked on GeeksForGeeks POTD on 18th January 2023. This problem has an easy tag on the GeeksForGeeks Practice platform.

Problem: Given a singly linked list of N nodes. Find the first node of the loop if the linked list has a loop. If a loop is present then return the node data of the first node of the loop else return -1.

I have discussed two working solutions to this problem from today's GFG POTD. In the optimal approach, we first detected a loop in the linked list. If it is found, then check for the starting node of the loop. We have used the 2-pointer algorithm to solve this problem efficiently.

I hope you found this video helpful!
