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

Given a non-empty 2D matrix Matrix and an integer K, find the max sum of a rectangle in the matrix such that it sum is no larger than K.Example:Given matrix = [ [1, 0, 1], [0,-2, 3]]k = 2The answer is 2 . Because The sum of rectangle is 2 and 2 is the [[0, 1], [-2, 3]] max number no larger than k (k = 2).Note: The rectangle inside the matrix must
