Guess the Price

In the television program "Shopping Street" of CCTV-2, two people, A and B are guessing price of a given item. You are asked to decide whose price is closer to the real price.

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.

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