注意看define，马蜂有点迷惑

#include<bits/stdc++.h>
#define int long long
#define r p
const int N=1e7;
int t,r;

using namespace std;
int inv[N+10];

int prime[N+10];
bool isprime[N+10];
int sum[N+10];//在m的阶乘中所有质因子 的(pi-1)/pi积
int sumnow=1;//当前结果
int cnt=0;
void init() {
	inv[1]=1;
	jc[0]=1;
	for(int i=1; i<=N; i++) {
		jc[i]=jc[i-1]*i;
		jc[i]%=p;
	}
	for(int i=2; i<=N; i++) {

	}

			prime[++cnt]=i;
			sumnow*=(i-1)*inv[i]%p;

		}
		for(int j=1; prime[j]*i<=N; j++) {

		sum[i]=sumnow;
	}
}
signed main() {
