http://poj.org/problem?id=3258 题意:有一条很长很直的河距离为L,里边有n块石头,不包括起点和终点的那两块石头,奶牛们会从一个石头跳到另外一个,但因为有的石头隔得太近了,所以需要删除m块石头,来增大石头之间的最小距离.求删掉m块石头之后的其中两块石头的最小距离 . 思路 :这个题的和3273思路代码都很像,不过这个可能难理解一点,也是二分的思路. #include<iostream> #include<stdio.h> #include<stdl…

/** 大意:给定n个点,删除其中的m个点,其中两点之间距离最小的最大值 思路: 二分最小值的最大值---〉t,若有距离小于t,则可以将前面的节点删除:若节点大于t,则继续往下查看 若删除的节点大于m,说明t,过于大,需要减小:若删除的节点小于m说明t过于小了,t需要增大 **/ #include <iostream> #include <algorithm> using namespace std; ]; int main() { long long l,n,m; cin>…
