状压以后,直接暴力枚举,2^20约等于1e6,而且满足bitcount = m的状态很少. #include<bits/stdc++.h> using namespace std; +; double x[maxn],y[maxn],z[maxn]; double d[maxn][maxn]; double squ(double x) { return x*x; } double dist(int i,int j) { return squ(x[i]-x[j])+squ(y[i]-y[j])+…

题目链接:http://codeforces.com/contest/673/problem/C 题意:给一串数,不同大小的区间内出现次数最多的那个数在计数的时候会+1,问所有区间都这样计一次数,所有的数字的计数结果.如果有数字出现次数相同多,取最小的那个. 数据<=5000,那就暴力枚举每一个区间,每次维护当前出现最多次数和当前需要计数的那个数,每次更新一个值,那最大值就是这个值或者是之前存好的.每次判断就可以了,注意相同的时候取最小的那个数. /* ━━━━━┒ギリギリ♂ eye! ┓┏┓┏…

题目大意: 有n次操作,每次都是对一根线中的一段区间进行染色(颜色并不相同),有时候后面的颜色有可能覆盖前面的颜色,问最后涂完色,能看到的颜色有几种,每种颜色有几部分? 解题思路: 这个题目建树的时候有些不同,并不是以点为对象,而是以区间为对象,很明显是对线段树的区间进行操作,更新的时候要以区间为单位,还有就是计算每个区间出现几次的时候可以根据线段树的建树特征对树进行遍历求解. #include <cstdio> #include <cstring> #include <io…
