#include
using namespace std;

int main() {
int a,b, c;
cin>>a>>b>>c;
int ans = 1;
a = a%c;
for(int i = 1; i<=b;i++)
{
ans = (ans * a)%c;
}
}

Your code is failing large test cases
For Eg:
Input: 967891 9234 198011
Your O/P: -116687
Correct O/p: 159864
This video teaches an interesting concept, refer it:
