Title description

"What's for dinner?" Lazy_sheep's girlfriend asked.
"We just finished lunch!" Lazy_sheep looked at the restaurant's recipe and replied helplessly.
As a century-old problem, "what to eat for dinner" has always plagued Lazy_sheep.
It is known that a positive integer is written before each dish in the restaurant's recipe as the dish number, and his girlfriend can remember which dishes he ate for the first n meals. If today's dinner is the same as one of the previous n meals, she will be unhappy.
Now Lazy_sheep casually said a certain number w, please help to determine if it will cause your girlfriend to be unhappy.

Input data

There is an integer t (1 ≤ t ≤ 100) in the first line, which means there are t groups of data. For each set of data: the
first row has a positive integer w (1 ≤ w ≤ 50), which represents the dish number spoken by Lazy_sheep; the
second row has a positive integer n (1 ≤ n ≤ 20); the
third row has n A different positive integer ai (1 ≤ i ≤ n, 1 ≤ ai ≤ 50), which represents the number of the dishes eaten for the first n meals.

Output Data

For each set of data: if w is the number of the dishes eaten in the first n meals, output a line of "unhappy", otherwise output "happy".
