Finding Next Greater Node in Linked List | Smart Sessions
In this video, our instructor Devi Prasad walks you through the process of finding next greater node in a linked list making it easy to follow along, even for beginners. By the end of the video, you'll have a solid understanding of how to solve similar problems and optimize your code for better performance.
Here’s the problem statement
You are given the head of a linked list with n nodes.
For each node in the list, find the value of the next greater node. That is, for each node, find the value of the first node that is next to it and has a strictly larger value than it.
Return an integer array answer where answer [i] is the value of the next greater node of the ith node (1-indexed). If the ith node does not have a next greater node, set answer [i]=0.
