 # [Codeforces]- Help needed in Double Cola problem.

Problem Code -Double Cola

I have understood the pattern that we have there. But, I am having some difficulties in implementing it. Please help me in devising the solution to this problem.

There is probably a more efficient way, but in this case you can simply simulate it. Start by subtracting 51, then 52, 54, 52^3 … while n does not become negative. Divide the result by the current power of two and you have the position in the initial query (0-based)

Thanks but I figured it out and now I have done it Actually I was able to figure out the solution to this question. I felt like I should be sharing it here, so here it is.

``````//JUST LIKE ANIMALS !!!!

#include<bits/stdc++.h>
using namespace std;
typedef long long ll;

int main(){
ll n,i;cin>>n;
ll c=1;
while(c*5<n){
n-=c*5;
c*=2;
}
//cout<<--n/c;
ll tmp=(n-1)/c;
switch(tmp){
case 0:cout<<"Sheldon";break;
case 1:cout<<"Leonard";break;
case 2:cout<<"Penny";break;
case 3:cout<<"Rajesh";break;
case 4:cout<<"Howard";break;
}
return 0;
}``````

``````int main()
