题目大意: 默认从零点开始 给定n次x y上的移动距离 组成一个n边形(可能为凹多边形) 输出其 内部整点数 边上整点数 面积 皮克定理 多边形面积s = 其内部整点in + 其边上整点li / 2 - 1 那么求内部整点就是 in = s + 1 - li / 2 求整个多边形边上的整点数 //求两点ab之间的整点数 int lineSeg(P a,P b) { int dx=abs(a.x-b.x), dy=abs(a.y-b.y); && dy==) ; ; // 不包括a b两个顶…

题目:http://poj.org/problem?id=1265 题意:已知机器人行走步数及每一步的坐标   变化量 ,求机器人所走路径围成的多边形的面积.多边形边上和内部的点的数量. 思路:1.以格子点为顶点的线段,覆盖的点的个数为GCD(dx,dy),其中,dxdy分别为线段横向占的点数和纵向占的点数.如果dx或dy为0,则覆盖的点数为dy或dx. 2.Pick公式:平面上以格子点为顶点的简单多边形,如果边上的点数为on,内部的点数为in,则它的面积为A=on/2+in-1. 3.任意一个…
