题目链接: http://codeforces.com/contest/673/problem/C 题解: 枚举所有的区间,维护一下每种颜色出现的次数,记录一下出现最多且最小的就可以了. 暴力n*n. #include<iostream> #include<cstdio> #include<cstring> #include<algorithm> #include<vector> using namespace std; ; const int…

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! ┓┏┓┏…

http://codeforces.com/problemset/problem/673/C 先说一个枚举区间的技巧,枚举前缀,不要枚举后缀. 就是下面这个代码是不好的 ; i <= n; ++i) { ; j <= i; ++j) { 区间[j, i] } } 为什么呢?就是很多东西重复了,而且也被迫用不上.只能老老实实地计算. 但如果考虑下枚举前缀. ; i <= n; ++i) { for (int j = i; j <= n; ++j) { 区间[i, j] } } 则能用…

Given an array with n objects colored red, white or blue, sort them so that objects of the same color are adjacent, with the colors in the order red, white and blue. Here, we will use the integers 0, 1, and 2 to represent the color red, white, and bl…
