Title Link:HDU-1506a histogram is a polygon composed of a sequence of rectangles aligned at a common base line. The rectangles has equal widths but could have different heights. For example, the figure on the left shows the histogram that consists of rectangles with the Heights 2, 1, 4, 5, 1, 3, 3, Measured in units where 1 is the width of the rectangles:Usually, histograms is used to represent discrete distributions, e.g., the frequencies of characters in texts. Note the order of the rectangles

Document directory 2. Method for Calculating the range of Path. 1. With such a framework, it is very easy to add new graphic elements, as is the image class. For more information about the series of directories, see. This section mainly solves three problems: finding the external rectangle of any geometric image. This external rectangle will be used in performance optimization. Of course, it is not on

Given a 2D binary matrix filled with 0‘s and 1‘s, find the largest rectangle containing all ones and return its area. Difficulty: 90 This is a very comprehensive question. We need to find the largest full 1 matrix in the 0-1 matrix. I can't start with this question. brute force is just a look at each matrix. There are a total of M (m + 1)/2 * n (n + 1) /2 sub-matrix (similar to a string sub-string, the number of sub-strings of a string is n (n + 1)/2,

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.See this problem, I feel a bit difficult, I have no idea, not how to solve this type of problem, even for test instructions also understand wrong (think is calculate coincident area)This problem is very simple if i

Datum points can be set to "anywhere" in the bounding rectangle(Location Select specific View http://bbs.fishc.com/thread-49489-1-1.html)1) and the understanding of the bounding rectangle:1.1) is not the inner border of the window.1.2) But the outer border of the string itself ~ ~2) The coordinates you set will be the coordinates of the Datum point ~ ~Once you know this, it's easy to achieve what's right.LR
