# largest rectangle in histogram grandyang

Learn more about blocking users. Suppose we have a list of numbers representing heights of bars in a histogram. Problem. Problem Given an Integer representing number of bars in a Histogram and an array of integers representing the height of the bars in the given Histogram. For simplicity, assume that all bars have the same width and the width is 1 unit. Given n non-negative integers representing the histogram's bar height where the width of each bar is 1, find the area of largest rectangle in the histogram. Block or report user Block or report grandyang. Above is a histogram where width of each bar is 1, given height = [2,1,5,6,2,3]. In this post, we will see about how to find largest rectangular area in a Histogram. So, if the input is like nums = [3, 2, 5, 7] Find the largest rectangular area possible in a given histogram where the largest rectangle can be made of a number of contiguous bars. Block user. Input: The first line contains an integer 'T' denoting the total number of â¦ Follow. For simplicity, assume that all bars have same width and the width is 1 unit. Largest Rectangle in Histogram. Find the largest rectangular area possible in a given histogram where the largest rectangle can be made of a number of contiguous bars. For example, consider the following histogram with 7 bars of heights {6, 2, 5, 4, 5, 1, 6}. The problem of finding the largest rectangle in a histogram is a very interesting one. Previous Next If you want to practice data structure and algorithm programs, you can go through 100+ data structure and algorithm programs. Lets take the example [2, 1, 5, 6, 2, 3] Lets start by thinking of a brute force, naive solution. For example: hist=[2,3,1,4,5,4,2] Find the largest rectangular area possible in a given histogram where the largest rectangle can be made of a number of contiguous bars. The largest rectangle is shown in the shaded area, which has area = â¦ Contact GitHub support about this userâs behavior. Given n non-negative integers representing the histogramâs bar height where the width of each bar is 1, find the area of largest rectangle in the histogram.. For simplicity, assume that all bars have same width and the width is 1 unit. Given n non-negative integers representing the histogramâs bar height where the width of each bar is 1, find the area of largest rectangle in the histogram. We have to find area of the largest rectangle that can be formed under the bars. The largest rectangle is shown in the shaded area, which has area = 10 unit. Intuition. Block user Report abuse. Solution: Assuming, all elements in the array are positive non-zero elements, a quick solution is to look for the minimum element h min in the array. Grand Yang grandyang. Then numElements * h min can be one of the possible candidates for the largest area rectangle. grandyang Follow. Largest rectangle in a histogram Problem: Given an array of bar-heights in a histogram, find the rectangle with largest area. Above is a histogram where width of each bar is 1, given height = [2,1,5,6,2,3]. Prevent this user from interacting with your repositories and sending you notifications.
