我的#define ll long long怎么了？感谢您给我解答，定给您点关注

#include<iostream>
#include<cstring>
#include<cstdio>
#define ll long long
using namespace std;
const ll mol=100003;
ll m,n;
ll km(ll di,ll zhi){
	ll ans=1,ll cj=di;
	while(zhi>0){
		if(zhi&1==1){
			ans=((ans%mol)*(cj%mol))%mol;
		}
		cj=((cj%mol)*(cj%mol))%mol;
		zhi=zhi>>1;
	}
	return ans;
}
int main(){
	//freopen("prison.in","r",stdin);
	//freopen("prison.out","w",stdout);
	cin>>m>>n;
	cout<<(km(n,m)%mol-((n%mol)*(km(m-1,n-1)%mol))%mol)%mol;
	return 0;
}
