题意: 求两条空间直线的距离,以及对应那条距离线段的两端点坐标. 思路: 有一个参数方程算最短距离的公式, 代入求即可. 但是这题卡精度... 用另外的公式(先算出a直线上到b最近的点p的坐标, 再算出b直线上到a最近的点q的坐标, 再求这两点距离)用double可以过, 直接参数方程的公式用long double才可以><而且下来交的时候..C++->WA,G++->AC... long double #include<cstdio> #include<cstr…

空间异面直线的距离直接套模板. 求交点:求出两条直线的公共法向量,其中一条直线与法向量构成的平面 与 另一条直线 的交点即可.还是套模板o(╯□╰)o 1.不会有两条线平行的情况. 2.两条直线可能相交 #include <cstdio> #include <cstdlib> #include <cstring> #include <algorithm> #include <cmath> using namespace std; ; ; stru…
