Two of them are equal, but the third one is different from the other two. Find the value that occurs exactly once.InputThe 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.OutputFor each test case, output the value that occurs exactly once.ExampleInput
