题意: 给出三角形的三个点的坐标(浮点数),     问落在三角形内及三角形边上的整点有多少? 思路:所有点暴力判断(点的范围1-99,三角形可能是0-100,因为这个WA了一下orz) AC代码: #include<cstdio> #include<cmath> #include<algorithm> #include<iostream> #include<cstring> using namespace std; typedef long l…

题目大意:果园里的树排列成矩阵,它们的x和y坐标均是1~99的整数.输入若干三角形,依次统计每一个三角形内部和边界上共有多少棵树. 三角形P0P1P2有向面积为A:2A = x0y1 + x2y0 + x1y2 - x2y1 - x0y2 - x1y0.如果三角形的三个顶点呈逆时针排列,那么有向面积为正,如果是顺时针排列,则有向面积为负.假设输入三角形为ABC,待判断点为O,则O在三角形ABC内部或边界上当且仅当SABC = SOAB + SOBC + SOAC.通过对有向面积取绝对值可以避免三…
