Hello codeforces, I was solving https://oj.uz/problem/view/IOI22_fish, and in general some OI problems come in different files one for grading and one for writing the solution. The problem is: how to get advantage from the .sh files, and if I am using windows how do I run them ? I know the system used in IOI is linux, so do participants of the IOI simply execute the run_cpp.sh file and the terminal will wait for input then provide output based on the solution?

Me, abd_ka, Abdalrhman (and De3b0o unofficially ) will race to the candidate master, and the loser (the last one of us) will replace his affiliation to "The winner's" fans club and will put the winner's photo showing that this person is his superior !! :>.

So excited to be the first and I'm afraid to be the last.. On a scale from 1 to 10, how hard is transforming from expert to candidate master ?
