Monocarp is going to register on the Codeforces website, but he can't come up with a sufficiently secure password. The requirements that his password must meet are as follows:

the password must consist of digits, as well as uppercase and lowercase letters of the Latin alphabet;
there must be exactly $$$a$$$ digits, exactly $$$b$$$ uppercase letters, and exactly $$$c$$$ lowercase letters;
for security, no two adjacent characters in the password should be the same. The lowercase and uppercase versions of the same letter are considered different characters.

Write a program that generates a password that meets all the requirements.

Input

The first line contains a single integer $$$t$$$ ($$$1 \le t \le 1000$$$) — the number of test cases.

Each test case consists of one line containing three integers $$$a$$$, $$$b$$$, and $$$c$$$ ($$$1 \le a, b, c \le 10$$$).

Output

Password Generator
