AtCoder Beginner Contest 171 - αlphabet

An uppercase or lowercase English letter \alpha will be given as input.
If \alpha is uppercase, print A; if it is lowercase, print a.

-----Constraints-----
 - \alpha is an uppercase (A - Z) or lowercase (a - z) English letter.

-----Input-----
Input is given from Standard Input in the following format:
α

-----Output-----
If \alpha is uppercase, print A; if it is lowercase, print a.

-----Sample Input-----
B

-----Sample Output-----
A

B is uppercase, so we should print A.
