Kth root - using power function gives huge number

#1

Getting huge number while calculating power.

#2

if you are using inbuild pow() function
then why you make this function

long long int calPower(long long int x,int y){

    if(y==0){

        return 1;

    }else{

        long long int temp = pow(x,y/2);  //getting huge number here, how to rectify this

        if(y%2==0){

            return temp*temp;

        }else{

            return x*temp*temp;

        }

    }

}

i think pow function will not create problem
here is my code i have also used it and it worked

but if you want you can build your own function like this

I have taken reference from here - https://www.geeksforgeeks.org/floor-value-kth-root-of-a-number-using-recursive-binary-search/
