You are given three digits $a$, $b$, $c$. Two of them are equal, but the third one is different from the other two.

Find the value that occurs exactly once.

Input

The first line contains a single integer $t$ ($1 \leq t \leq 270$) — the number of test cases.

The only line of each test case contains three digits $a$, $b$, $c$ ($0 \leq a$, $b$, $c \leq 9$). Two of the digits are equal, but the third one is different from the other two.

Output

For each test case, output the value that occurs exactly once.
