题解:

等比数列:{a,aq1,aq2,aq3,aq4,aq5...aqn,...}

前m项的前缀和:s=a(1-qm)/(1-m);

费马小定理:若p为质数,ap-1%p=1

逆元:若ax%p=1(p为质数),则a,x互为逆元

则ans=sigma(1,n)q(1-qm)/(1-m)

由于同余定理不支持除法,逆元处理:

ans=sigma(1,n)q(1-qm)/(1-q)mod-2

考虑到负数问题

ans=sigma(1,n)q(qm-1)/(q-1)mod-2

最终

  ans=sigma(1,n)q(qm-1)/(q-1)mod-2

代码:

#include<cstdio>
#include<iostream>
#define ll long long
using namespace std;
const ll mod=1e9+;
ll n,m;
inline ll fpow(ll a,ll p){
ll res=;
for(;p;p>>=,a=a*a%mod) if(p&) res=res*a%mod;
return res%mod;
}
inline void solve(){
ll ans=n;
for(ll i=,tmp,s;i<=n;i++){
/*自己推的*/
//tmp=fpow(i,m+1);
//s=((tmp-1+mod)%mod)*fpow(i-1,mod-2)%mod;
//ans=(ans+s-1+mod)%mod;
/*学哥讲的等比数列*/
tmp=i*(fpow(i,m)-)%mod;
s=fpow((i-),mod-);
ans=(ans+tmp*s%mod)%mod;
}//应该是都对
cout<<ans%mod;
}
int main(){
ios::sync_with_stdio(false);
