Is l1-031 too fat (10 points)

L1-031 Is it too fat (10 branch )

It is said that a person's standard weight should be his height （ Company ： centimeter ） subtract 100、 Multiplied by 0.9 The kilogram obtained . The error between the real weight and the standard weight is 10% Inside is the perfect figure （ namely | True weight − Standard weight | < Standard weight ×10%）. It is known that the market weight is twice the kilogram . Now give a group of people's height and actual weight , Please tell them if they are too fat or too thin .

Input format ：
The first line of input gives a positive integer N（≤ 20）. And then N That's ok , Each line gives two integers , They are the height of a person H（120 < H < 200; Company ： centimeter ） And real weight W（50 < W ≤ 300; Company ： Jin ）, Separated by spaces .

Output format ：
Output a line of conclusions for everyone ： If it's the perfect body , Output You are wan mei!; If it's too fat , Output You are tai pang le!; Otherwise output You are tai shou le!.

sample input ：

3
169 136
150 81
178 155

sample output ：

You are wan mei!
You are tai shou le!
You are tai pang le!
