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 * $1 \leq x \leq 1000$ * $1 \leq a \leq 1000$ * $1 \leq b \leq 1000$ * $x, a$ 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: $x$ $a$ $b$ [samples]
Samples
Input #1
5 2 7
Output #1
B

The distances between Snuke's residence and stores $A$ and $B$ are $3$ and $2$, respectively. Since store $B$ is closer, print `B`.
Input #2
