I was reviewing the first solvers of today contest and I saw this: 290888047 I don't think anyone can think, write, submit this code in 1:14 minutes

can you do it?

Each contest I participate , When I make a wrong submition I become so stressful and I can't think anymore , start making false submisions changing silly thing in code

And you can notice that I am stuck on the same level for long time ( from 1140 -> 1198 ) any suggestions?
