Next Greater Element | C++ | Find the next greater element for every array element (use of stack)

In this video, we are going to look at a tricky question of
stack: next greater element

Description: Given an array arr[ ] of size N having distinct elements, the task is to find the next greater element for each element of the array in order of their appearance in the array.
Next greater element of an element in the array is the nearest element on the right which is greater than the current element.
If there does not exist next greater of current element, then next greater element for current element is -1. For example, next greater of the last element is always -1.

In this video, you’ll also learn about asymptotic notations, they are basically mathematical notations which represent order of growth of any mathematical function. There are three famous notations which you’ll see in this video, they are big O , Theta , Omega.

Welcome to the first video Tutorial on Data Structures And Algorithms. In this video I am going to provide an Introduction to Data Structures And Algorithms. This Course is created to Explain the Fundamentals of data structures and algorithms. This video Will explain What is data?, What is data structure?, The Need for Data Structures, What is algorithm?
