Why my code is giving wrong input for 10^15 10

#1

#include<bits/stdc++.h>
#include<math.h>
#define ll long long
using namespace std;
int main(){
int t;cin>>t;
while(t–){
ll n, k;cin>>n>>k;
ll s=1,e=n;
ll ans=0;
while(s<=e){
ll mid=(s+e)/2;
ll f=pow(mid,k);
//cout <<mid<<",";
if(f<=n)ans=mid,s=mid+1;
else e=mid-1;
}
cout<<ans<<endl;
}
}

Hey @argus
Don’t use the pow function because it can lead to overflow so instead calculate power using a loop and if it exceeds n then break.
10^8 now if u try to compute power(10^8,10) then this will lead to overflow
