Next Greater Element using Stack | Next Greater in Array | Programming Tutorials
In this tutorial, I have explained multiple approaches to find next greater element in array. Also, how we can find next greater element using stack.
Java code to find first greater element on the right side of every element of an array - https://webrewrite.com/java-program-f...
Given an input array, find the next greater element for every element of an array. The next greater element x is the first greater element on the right side of x in an array. If no next greater element is found then consider -1.
In this tutorial, I have explained how to find next greater element using stack.
For example :
Example 1 -
Input = {4, 2, 6, 8, 1, 0}
Output = {6, 6, 8, -1, -1, -1}
Example 2 -
Input = {7, 8, 1, 4}
Output = {8, -1, 4, -1}
