秦始皇统一中国之后要在全国修公路连接各个城市,皇帝只想修成最小生成树(距离最小,不考虑人力),一个道士说自己可以不花人力物力修一条路,经过两方妥协,选择max(两个城市人口/(生成树长度-这条路的长度(连接两个城市的路中,权值最大的那段路)))的路让他变,求这个比值最大值. #include <iostream> #include <cstdio> #include <sstream> #include <cstring> #include <map&…

Qin Shi Huang's National Road System HDU - 4081 感觉这道题和hdu4756很像... 求最小生成树里面删去一边E1 再加一边E2 求该边两顶点权值和除以(最小生成树-E1)的最大值 其中(最小生成树-E1)必须是最小的 先跑一遍prim 跑完之后在最小生成树里面dp dp[i][j] = i到j的路径中最大的那条边 最小生成树减去dp[i][j]肯定会最小 代码如下 #include <cstdio> #include <algorithm…
