Took me a few minutes to understand whats going on :D
Good Job!

Thanks for the answere but my solution without doubles would fail so i had to try a different approach. It took me some time to solve it -_-

Your solution fails due to precision loss and rounding errors. You need to keep your calculations precise, for example by avoiding double and using integers all the time.

Hey i saw your solution and i am not understanding how it works. Can you please explain me why this works for long long but not for double?

Thank you, kind man.

In description said "population greater than or equal... " in fact population should be only greater, you will have 1 condition fail till leave only greater condition. It is descriprion of aaasigment or input data mistake.

Got a problem here.
I pass every basic test and when i try to attempt i pass the random test but not the fixed test were the output should be 50 (mine is 51).
Dont know where my problem is.
