One day, Fat Brother meet N monsters, but he only take his “Gorehowl”.

Each monster has health points. When Fat Brother attacked a monster, the monster’s health points will decrease damage points of “Gorehowl”. If a monster’s health points less than or equal to zero, it die. Fat Brother must kill all monsters or he can’t get away from here. If he can kill all monster, he want to know least of times he should attack. If he can’t, he will choose go die.

Input

There are multiple test cases. The first line of input contains an integer T (T <= 50) indicating the number of test cases. For each test case:

The first line contains one integer N (1 <= N <= 100000) means number of monsters.

The next line contains N number Hi (1<= Hi <= 10) means monster’s health points.

Output

If Fat Brother can kill all monsters, output a number means least of times Fat Brother should attack. Otherwise output “Fat Brother choose go die”

+ 5 + 4 + 3 + 2 + 1 = 28, kill all monster.

Third

case, Fat Brother can’t kill first monster, so he will choose go

die.

The test sample just explain problem, you can think the realy data is accord with the title’s description
