A - Meal Delivery

Time limit : 2sec / Memory limit : 256MB
Score : 100 points
Problem Statement
Snuke lives at position x on a number line. On this line, there are two stores A and B, respectively at position a and b, that offer food for delivery.
Snuke decided to get food delivery from the closer of stores A and B. Find out which store is closer to Snuke's residence.
Here, the distance between two points s and t on a number line is represented by |s−t|.
Constraints
1≤x≤1000
1≤a≤1000
1≤b≤1000
x,a and b are pairwise distinct.
The distances between Snuke's residence and stores A and B are different.

Input
Input is given from Standard Input in the following format:
x a b
Output
If store A is closer, print A; if store B is closer, print B.

Sample Input 1
Copy
5 2 7
Sample Output 1
Copy
B
The distances between Snuke's residence and stores A and B are 3 and 2, respectively. Since store B is closer, print B.

Sample Input 2
Copy
1 999 1000
Sample Output 2
Copy
A
