{
unsigned long long int a;
cin>>a;
for(int i=0;i<a;i++)
{
unsigned long long int no,power;

cin>>no>>power;
unsigned long long int start=0,end=no,mid,ans;

while(start<=end)
{ 
    mid=(start+end)/2;
 unsigned long long int d=1;
 for(int i=1;i<=power;i++)
 d=d*mid;
 if(d == no )
    {
       ans=mid;
       break;
    }
  else if(d > no)
    {
            end =mid-1;
    }
    else 
    {
        start=mid+1;
    ans=mid;
        
    }
}
cout<<mid<<endl;
}

}

Hi @Lovishbansal,
here is d updated code https://codeshare.io/5ZVwWV
instead of storing power, directly use pow function. since long long can store value<=10^18, if pow is stored, it will contain garbage value if value stored is > 10^18.
Hope dis resolves ur doubt.
