IDrandom的专栏

这是我做过的最sb的一场div2，没AK有点可惜，F有些小trick 670A holidays 根据%7的结果判一下就好了#include<cstdio>#include<cstdlib>#include<cstring>#include<cmath>#include<iostream>#include<vector>#include<set>#include<queue>

Problem A 这是一个sb题，统计一下比较哪个多就好了#include <bits/stdc++.h>using namespace std;typedef long long LL;const LL mod = 1e9+7;const int INF = 0x3f3f3f3f;char str[200050];int main(void){ int n;
