Hello, Codeforces!

Yesterday, in CF Round 366 my friend Birjik encountered a strange problem. His correct code was receiving Runtime Error in sample case.

Take a look at these codes:
Runtime error
Accepted

As you can notice, one code has these lines:

ios_base::sync_with_stdio(0);
cin.tie(0);

Strange, isn't it?
As I have understood, this happens because of an array called read.
Renaming that array solves this problem.

Long story short, using ios_base / cin.tie receives runtime error if we have a variable named read in our code.
Be careful!
