Problem descriptionn adjacent rectangles are placed on the horizontal axis, the width of each rectangle is 1, and the height of the first (1≤i≤n) rectangle is hi. These n rectangles form a histogram. For example, the height of the six rectangles is 3, 1, 6, 5, 2, 3, respectively. Find the rectangle with the largest area in the given histogram, and its edges

DescriptionA 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,

Question:Bob can draw a horizontal line in an original blank rectangle or an empty rectangle separated by a vertical line, and vice versa.After the line is drawn, Bob selects two target points in the original rectangle, and the target point is not on the painting line. Alice can delete the line to make the two points in the same empty

In the process of doing an Android project, we always encounter the need to use rounded rectangle controls to display icons, pictures, or buttons, one solution is to create a shape layout XML file under Drawable, and a custom control class that inherits from ImageView. Here is a concrete way to achieve this.First we name a Xcroundrectimageview class and inherit from ImageView. The code is as follows:1 ImportAndroid.content.Context;2 ImportAndroid.grap

Take a rectangle with a circumference of 24 centimeters as an example, the following steps are specified: 1. Use the Point tool to draw a point and mark the Text tool as point A. Select Point A, perform the transform-translate command, in the pop-up dialog box, make the following settings: Select the rectangular coordinates, the "horizontal direction" of the "fixed distance" defaults to 12, "vertical" "Fixed distance" default to 0, and finally click

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
