A little known fact is that cats really love solving captchas! Today, Mimi the cat has prepared some captcha puzzles by drawing digits out of asterisks.

The numbers are drawn as follows:

Digit | Drawing | Digit | Drawing |
---|---|---|---|

0 | -*-*-*- |
1 | ------* |

2 | -*-*-*- |
3 | -*-*-*- |

4 | *-----* |
5 | -*-*-*- |

6 | -*-*-*- |
7 | -*-*-*- |

8 | -*-*-*- |
9 | -*-*-*- |

Mimi can scale the numbers up and down by adding or removing asterisks from each edge. For example, the following are all the number 0:

```
-*-
*-*
*-*
---
*-*
*-*
-*-
```

```
-*-*-
*---*
-----
*---*
-*-*-
```

```
-*-*-*-
*-----*
*-----*
*-----*
-------
*-----*
*-----*
*-----*
-*-*-*-
```

Note that all horizontal segments are of the same length, and all vertical segments are of the same length. Mimi may also add additional dashes as padding around the digits. Note that the padding can include extra lines consisting only of dashes before and after the actual number.

Mimi just has one little problem - she needs someone else to make sure she solved her puzzles correctly! Can you help your good friend Mimi?

in a horizontal segment.
