## Task Description

Determine the $A$ and $B$ values for two input numbers. You will be given two numbers, each consisting of 4 different digits from 1 to 9. You should determine two values. The $A$ value is the number of digits that are the same and appear in the same locations. For example, the $A$ value of `1234`

and `1253`

is two, since both 1 and 2 are the same and they appear in the same locations. The $B$ value is the number of digits that are the same but appear in different locations. For example, the $B$ value of `1234`

and `1253`

is 1, since 3 appears in both numbers but appear in different locations.

## Input Format

Two numbers in a line to determine. Both number are composed of 4 different digits without 0.

## Output Format

Single string of `n A m B`

where $n$ is the $A$ value and $m$ is the $B$ value determined for the input.

## Sample Input

`1234 1345`

## Sample Output

`1A2B`
