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, P_A, P_B (0 <= P_A, P_B <= P <= 100, P_A != P_B), 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.

Sample Input
