In the television program "Shopping Street" of CCTV-2, two people, A and B are guessing the 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 <= 20) indicating the number of test cases.

Each case contains three integers in one line: P, PA, PB (0 <= PA, PB, P <= 100, | PA – P | != | PB – P |), 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.
