Train of thought: if the time complexity requirement is O (n 2 ), the solution is more and better understanding. For example, you can traverse the column at the current I position, calculate the maximum rectangle ending with this I column, and then

The intersection of Any Polygon and rectangle is actually to judge whether multiple line segments are intersecting with this rectangle. The simple point is to determine whether a line segment is intersecting with each side of the rectangle. Now

Alice comes up with a new game and wants to play with Bob.
There is one rectangle on the paper initially, we define its lower-left corner's

The following three plot functions need a pointer to the rectangular structure:
Fillrect (HDC, & rect, hbursh); // fill
Framerect (HDC, & rect, hbrush); // empty
Invertrect (HDC, & rect); // internal Inversion
Case wm_paint: HDC = beginpaint (hwnd, &

largest Rectangle in a histogramA 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

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

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
