Flavors X76679

I am going to have ice cream with my friends, and I don’t know which flavor I should order. Since I like letters, my favorite flavor is the one that comes first in alphabetical order.

Input

The input consists of multiple test cases. Each test case starts with a number $N$ of choices on a single line, satisfying $1\leq N\leq 10$. On the next line are $N$ different names of ice cream flavors. The input ends with the value $0$ on a single line, which should not be processed.

Output

For each test case, write the following on a single line:
My favorite flavor is X
Here, X is the flavor I prefer among the different choices.
