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.
