AC代码:
#include <iostream> #include <cstdio> using namespace std; int mod_exp(long long a,long long b,int m) { int temp=1; a=a%m; while(b) { if(b%2==1) temp=temp*a%m; a=a*a%m; b>>=1; } return temp; } int main(void) { freopen("in.txt","r",stdin); long long T; scanf("%lld",&T); while(T--) { long long n; int temp,m=10; scanf("%lld",&n); temp=mod_exp(n,n,m); printf("%d\n",temp); } fclose(stdin); return 0; }
