Problem Description Given two rectangles and the coordinates of two points on the diagonals of each rectangle,you have to calculate the area of the intersected part of two rectangles. its sides are parallel to OX and OY . Input Input The first line…
描述 The Archeologists of the Current Millenium (ACM) now and then discover ancient artifacts located at vertices of regular polygons. The moving sand dunes of the desert render the excavations difficult and thus once three vertices of a polygon are di…
Given a 2D binary matrix filled with 0's and 1's, find the largest rectangle containing all ones and return its area. PS:将其化解为柱状图求最大体积的问题.先用动态规划的思路,将矩形中垂直方向的连续1的数量进行计算. 而后逐行扫描,并在扫描时将其转化为柱状图求体积. 即若高度一直增加,则持续压入栈,当出现h[i]<栈顶高度时,则出栈,并计算出栈元素的所在矩形的体积.持续计算直到…
