Codeforces Round #467 (div.2) 我才不会打这种比赛呢 (其实本来打算打的) 谁叫它推迟到了\(00:05\) 我爱睡觉 题解 A. Olympiad 翻译 给你若干人的成绩 让你划定一个分数线 使得所有不低于这个分数线的人都可以获奖 但是\(0\)分的人一定不能得奖 问你有多少种获奖情况 题解 \(sort+unique\) 然后判断一下最小值是不是\(0\)就行了 #include<iostream> #include<cstdio> #include…

A. Olympiad 给出n个数,让你找出有几个非零并且不重复的数 所以用stl的set //#define debug #include<stdio.h> #include<math.h> #include<cmath> #include<queue> #include<stack> #include<string> #include<cstring> #include<string.h> #include…

没有参加,但是之后几天打了哦,第三场AK的CF比赛. CF大扫荡计划正在稳步进行. [A]Olympiad 题意: 给\(n\)个人颁奖,要满足: 至少有一个人拿奖. 如果得分为\(x\)的有奖,那么任意得分大于\(x\)必须拿奖. 得分为\(0\)的人不能拿奖. 每个人的得分\(0\le x\le 600\),问有多少种颁奖方式? 题解: 本质上,问题可以转化为有多少种不同的得分.于是开一个桶做. #include<cstdio> int n,x,cnt[601],ans; int main…
