快速幂 A^B Mod C

C语言——A^B Mod C

在这里插入代码片
```#include<stdio.h>
long long pow(long long a,long long b,long long c){
	long long s=1;
	while(b){
		if(b%2) s*=a;
		a=(a*a)%c;
		b=b/2;
		s=s%c;
	}
	return s;
}


int main()
{
	long long a,b,c;
	scanf("%lld %lld %lld",&a,&b,&c);
	a%=c;
	printf("%lld",pow(a,b,c));
}
