输入输出格式

输入格式

The first line contains a single integer $ n $ ( $ 1<=n<=100 $ ). The next line contains an integer $ p $ $ (0<=p<=n) $ at first, then follows $ p $ distinct integers $ a_{1},a_{2},...,a_{p} $ $ (1<=a_{i}<=n) $ . These integers denote the indices of levels Little X can pass. The next line contains the levels Little Y can pass in the same format. It's assumed that levels are numbered from 1 to $ n $ .

输出格式

If they can pass all the levels, print "I become the guy.". If it's impossible, print "Oh, my keyboard!" (without the quotes).
