Input

There are multiple test cases. The first line of input is an integer T (T <= 10) indicating the number of test cases.

Each case contains three integers in one line: P, PA, PB (0 <= PA, PB <= P <= 100, PA != PB), indicating the real price, the price A guesses and the price B guesses.

Output

For each case, output “A” or “B” according to whose price is closer to the real price.
