Largest Rectangular Area in a Histogram, C++

In this video, we are going to look at a tricky question of stack: next greater element Description:Given an array of integers heights representing the histogram s bar height where the width of each bar is 1, return the area of the largest rectangle in the histogram. 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 l. .., ProgrammingKnowledge, DataStructuresAndAlgorithms, DataStructures, algorithm, Algorithms, AlgorithmsTutorial, DataStructuresTutorial, Arrays, Strings, Stacks 20220822 EEIN57vD3po
