Not A + B

You are required to print a value of $c$ which is not equal to the sum of two given numbers $a$ and $b$.

First line contains an integer $t$ --- number of tests. Next $t$ lines contain two integers $a$ and $b$ each.

You are required to output an integer $c$ for each test in a separate line. If there are multiple solutions, you may output any of them.

• $1 \le t \le 10^3$
• $1 \le a, b \le 50$
• $1 \le c \le 50$
