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.Find the area where two rectangles intersectVertical rectangles, each of which is represented by a coordinate of two points in the lower left a

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.Above is a histogram the where width of each bar is 1, given height = [2,1,5,6,2,3] .The largest rectangle is shown in the shaded area, and which has an area = 10 unit.For example,Given height = [2,1,5,6,2,3] ,Return 10 .Train of thought: This problem

Given a plurality of rectangles from left to right, it is known that this rectangle has a width of 1 and is not exactly equal in length. The rectangles are joined in a row, and the largest rectangular area within the range of these rectangles is obtained, and the area is printed out. The rectangle you are seeking can span multiple rectangles, but cannot exceed the range determined by the original rectangle.

This kind of rectangle box if use HTML4 can only use the background code to generate, now HTML5 provides the canvas function to be able to draw easily, therefore said HTML5 superiority is quite high.Here is a method--fillrect () from the literal meaning can also know that this is to fill a rectangle, here the parameters are worth explaining fillRect (X,y,width,height), this and the coordinates of mathematic
