Largest Rectangle in HistogramGiven 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 histo

Intersection I will give you a line segment, a rectangle, and ask if there is any intersection. Intersection: a line segment is completely intersecting within a rectangle. A line segment and a rectangle share an irregular intersection between any side. Idea: after knowing the detailed intersection rules, the question is actually not difficult, but there is also

Title Description: given the coordinates of a series of 2-dimensional planar points (x, y), where x and y are integers, a minimum rectangle box is required to have all the point frames. The edges of the rectangular box are parallel to the X and Y axes, and the points fall on the edges and are also framed. Input: The test input contains several test cases, each consisting of a series of coordinates

Question:Find the total area covered by and rectilinear rectangles in a 2D plane.Each rectangle was defined by its bottom left corner and top right corner as shown in the figure.Assume the total area is never beyond the maximum possible value of int.Analysis:Problem Description: Calculates the area covered by two matrices in a two-dimensional coordinate system. Each matrix is represented by its lower-left corner and the coordinates of the upper-right

ZOJ 3597Test instructions is said that there are n guns, there are m targets, each gun only one shot (that is, a gun can only hit a target), tell you the first gun to hit the first J target, and now the probability of the emergence of a continuous p gun, after knowing this p gun, you are allowed to choose a continuous q a target, The number of targets that this p has hit is the highest, and the expected number of targets to be hit.This problem can be transformed into another model by simply tran

Well, this problem looks easy at first glance. However, to get a bug-free code may is not this easy.The total square was simply equal to the sum of the area of the rectangles minus the area of their overlap. How does we compute the area of a rectangle? Well, the simply times its height and its width. The height and width can obtained from the coordinates of the corners.The key to this problem actually lies on how to handle overlap.First, let's think a

Analysis of LeetCode Maximal RectangleSolving LeetCode with Maximal Rectangle Original question A matrix contains only 1 and 0. Find the rectangle with the largest area containing only 1 and return its area. Note:The element type in the matrix is a string. Example: Input: matrix = [['1', '1', '0', '1', '0', '1'], ['0', '1', '0', '0', '1', '1'], ['1', '1', '1', '1', '0', '1'], ['1', '1', '1', '1', '0', '1']]

Description A histogram is a polygon composed of a sequence to rectangles at a aligned base line. The rectangles have equal widths but may have different. For example, the "figure on" the left shows the histogram, consists of rectangles with the Heights 2, 1, 4, 5, 1, 3, 3, Measured in units where 1 are the width of the rectangles: Usually, histograms are used to represent discre Te distributions, e.g., the frequencies of characters in texts. Note This order of the rectangles, i.e., their heig

This article mainly introduces the php method for drawing a rectangle, which involves the use of the imagerectangle method in the GD Library. For more information, see the example in this article.
