【HDOJ6666】Quailty and CCPC（模拟）

题意：给出罚时现场赛的题数和罚时，问是否有在金牌线下取整被卡出，四舍五入卡入的队伍

n<=1e5

思路：

 1 #include<bits/stdc++.h>
 2 using namespace std;

 4 typedef unsigned int uint;
 5 typedef unsigned long long ull;
 6 typedef pair<int,int> PII;

 8 typedef vector<int> VI;
 9 typedef vector<PII> VII;
10 #define N  110000

12 #define fi first
13 #define se second
14 #define MP make_pair
15 #define pi acos(-1)
16 #define mem(a,b) memset(a,b,sizeof(a))
17 #define rep(i,a,b) for(int i=(int)a;i<=(int)b;i++)
18 #define per(i,a,b) for(int i=(int)a;i>=(int)b;i--)
19 #define lowbit(x) x&(-x)
20 #define Rand (rand()*(1<<16)+rand())
