CF185C Clever Fat Rat

本题数据有误。

The Fat Rat and his friend Сerealguy have had a bet whether at least a few oats are going to descend to them by some clever construction. The figure below shows the clever construction. A more formal description of the clever construction is as follows. The clever construction consists of $ n $ rows with scales. The first row has $ n $ scales, the second row has $ (n-1) $ scales, the $ i $ -th row has $ (n-i+1) $ scales, the last row has exactly one scale. Let's number the scales in each row from the left to the right, starting from $ 1 $ . Then the value of $ w_{i,k} $ in kilograms $ (1

The first line contains a single integer $ n $ $ (1

Print "Fat Rat" if the Fat Rat is right, otherwise print "Cerealguy".

Notes to the examples: - The first example: the scale with weight capacity 2 gets 1. That means that the lower scale don't break. - The second sample: all scales in the top row obviously break. Then the oats fall on the lower row. Their total mass is 4,and that's exactly the weight that the lower scale can "nearly endure". So, as 4 $ >= $ 4, the scale breaks.
