CF1926A Vlad and the Best of Five

Vladislav has a string of length $ 5 $ , whose characters are each either $ \texttt{A} $ or $ \texttt{B} $ . Which letter appears most frequently: $ \texttt{A} $ or $ \texttt{B} $ ?

The first line of the input contains an integer $ t $ ( $ 1 \leq t \leq 32 $ ) — the number of test cases. The only line of each test case contains a string of length $ 5 $ consisting of letters $ \texttt{A} $ and $ \texttt{B} $ . All $ t $ strings in a test are different (distinct).

For each test case, output one letter ( $ \texttt{A} $ or $ \texttt{B} $ ) denoting the character that appears most frequently in the string.
