Largest Rectangle in Histogram: Given an array of integers A of size N. A represents a histogram i.e A[i] denotes height of the ith histogram’s bar. 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. An algebraic solution is presented below. Here's a solution based on the "Largest Rectangle in a Histogram" problem suggested by @j_random_hacker in the comments: [Algorithm] works by iterating through rows from top to bottom, for each row solving this problem, where the "bars" in the "histogram" consist of all unbroken upward trails of zeros that start at the current row (a column has height 0 if it has a 1 in the current row). 4 is an equation reducible to a quadratic type, that is, We have reached the most crucial point of this solution—we will make some mathematical manipulation to the discriminant. +51 −0 Data Structures/Stacks/Largest Rectangle/Solution.java +2 −1 README.md 51 Data Structures/Stacks/Largest Rectangle/Solution.java The area of the right triangle is given by (1/2)*40*30 = 600. The largest rectangle is shown in the shaded area, which has area = 10 unit. Problem with Solution BDEF is a rectangle inscribed in the right triangle ABC whose side lengths are 40 and 30. By admin. # for each bar (to say i), in which bar i is the shortest one. Figure 1 illustrates a possible input array and the corresponding solution. Required: Find the largest (most elements) rectangular subarray containing all ones. Editorial. largest-rectangle hackerrank Solution - Optimal, Correct and Working # All the bars in current zone [begin, end] have the same height. Solution for Find the area of the largest rectangle that can be inscribed in the ellipse x2/a2 + y2/b2 = 1. Solution to Problem: let the length BF of the rectangle be y and the width BD be x. THE PROBLEM: What is the area of the largest rectangle which can be inscribed in a circle of radius 1? Approach: In this post an interesting method is discussed that uses largest rectangle under histogram as a subroutine. h - the height of the rectangle defined by that point. But when I met with the question “Maximal Rectangle”, I realized the previous one is not the designed solution.
