## Solution
It is a number guessing game, and the correct number was generated by random function.
At first, I tried using the same random [generator](random.cpp) as the code and calculated the number using [script](random.py) but to no avail.
I figured that it was because the timezone problem, the srand(time(0)) was different in different timezone.
But I noticed that the server only took the remainder of the number generated divided by 10, and there were only 6 numbers that involved in calcluating the answer.

Therefore, I might be able to guess it by guessing a possible answer several time.
And that's how I got it right!
