【SPFA+二分答案】BZOJ1614- [Usaco2007 Jan]Telephone Lines架设电话线

沉迷于刷水以前的那个二分写法过不了QAQ 换了一种好像大家都比较常用的二分。原因还不是很清楚。【题目大意】给出一张图,可以将其中k条边的边权减为0,求1到n的路径中最长边的最小值。【思路】二分答案,即最长边的最小值x。对于每次check(x),我们将边权大于x的边设为1,边权小于等于x的边设为0,跑

POJ 1269 Intersecting Lines【判断直线相交】

题意:给两条直线,判断相交,重合或者平行思路:判断重合可以用叉积,平行用斜率,其他情况即为相交。求交点:这里也用到叉积的原理。假设交点为p0(x0,y0)。则有:(p1-p0)X(p2-p0)=0(p3-p0)X(p2-p0)=0展开后即是(y1-y2)x0+(x2-x1)y0+x1y2-x2y1=
