PROBLEM OF THE DAY : 13/11/2024 | Intersection Point in Y Shaped Linked Lists

Welcome to the daily solving of our PROBLEM OF THE DAY with Yash Dwivedi We will discuss the entire problem step-by-step and work towards developing an optimized solution. This will not only help you brush up on your concepts of Linked List but also build up problem-solving skills.

Given two singly linked lists, return the point where two linked lists intersect.

Note: If the linked lists do not merge at any point, return -1.

Examples:

Input: Linked list 1: 4->4->4->4->4, Linked list 2: 4->4->4
  Output: 4 Explanation: From the above image, it is clearly seen that the common part is 4->4 whose starting point is 4.

Give the problem a try before going through the video. All the best!!!
