standard output

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≤t≤2701≤�≤270) — the number of test cases.

The only line of each test case contains three digits a�, b�, c� (0≤a0≤�, b�, c≤9�≤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.
