Modular function

#1

why my code fail in many test case
#include
using namespace std;
int main() {
long long int x,y,z;
cin>>x>>y>>z;
int exp = 1;
for(int i = 1; i <=y;i++){

     exp = exp*x;
     
 }
 int k = exp % z;
 cout<<k;

}
and also correct my code

@kshitiz.gzb
You should the modulo with z at every iteration rather than just at the end.
exp = (exp*x)%z;
Make this change and try again.
