**There is a man named orange cat in Changsha University who has realized team Cai's famous saying**
The story is like this. Everyone knows that orange cat is a fake king and likes to pretend to be weak.
We are tired of fake's life, so we decided to tell the truth today, such as zmltxdy......
A total of n people participate, the number from 1 to N, each person will only report a label, suggesting that the person is better than him.
As we all know, * * strong is really strong, and fake is really fake, so you need to judge whether there are people lying today. Contradiction means that there are lies**
###Input format:
A $$t $$represents the number of test cases
The next $$n $$represents the number of people
Next line $$n $$integers $$a_ I $$, the number of $$I $$means that the $$I $$individual recognizes $$a_ I $$is better than him, if $$a_ If I $$is I, it means that the person thinks he is the strongest in the group
$$T<=100,n<=1e6,\sum{n}<=1e7 $$
###Output format:
If someone is lying, output fake, otherwise output cgltxdy
###Input example:
```in

three
3 1 2
four
