This is an old game for two players, often played with paper and pen. Modern version is also known as **Mastermind**.

First player, let it be Alice - chooses a secret `4`

-digit **code** (like `1492`

), with all digits different.

The second player, let it be Barbara - makes several attempts to guess this code. She can offer any combinations
of `4`

digits (without repetitions) - and for each attempt the Alice should answer with a hint.

The hint consists of two values:

- first tells how many digits are guessed correctly and are in correct positions;
- second tells how many digits are guessed correctly but are in wrong positions.

For example, if the secret value is `1492`

and Barbara's guess is `2013`

- Alice should answer with `0-2`

.

And if the guess is `1865`

, then the hint would be `1-0`

.

This game could also be played with `4`

-letter words, but in this case it may require the knowledge of the language.

Further information could be found in the dedicated wikipedia article.

Your goal is to write a program which calculates the values which should be told as a hint to the given guess.

**Input data** will contain the secret value and the number of guesses in the first line.

Second line will contain the specified amount of guesses.

**Answer** should contain hints for these guesses, they should be given in format `X-Y`

and separated with spaces.

Example:

```
input data:
1492 5
2013 1865 1234 4321 7491
answer:
0-2 1-0 1-2 0-3 2-1
```
