Minestro is recreating images on the Internet with his magic paint gun when he unexpectedly runs out of cartridges!

Minestro has access to a supply of cartridges in the three primary colors - red, blue and yellow. Each image is represented by a grid of rows and columns of cells that are all initially empty, with no paint of any color in any cell.

Minestro can consume a single paint cartridge with his gun to add paint of the color of the cartridge to a contiguous sequence of adjacent cells in a single row. It is possible for up to three cartridges to paint their color on the same cell, in which case the resulting color is a mixture of all colors applied, according to the following table:

Color | Symbol | Primary Colors to Mix |
---|---|---|

White | `.` |
None |

Red | `R` |
Red |

Blue | `U` |
Blue |

Yellow | `Y` |
Yellow |

Orange | `O` |
Red and yellow |

Green | `G` |
Blue and yellow |

Purple | `P` |
Red and blue |

Brown | `B` |
Red, blue, and yellow |

Minestro still has one image to paint, so he needs you to tell him the minimum number of red, yellow, and blue paint cartridges he needs to buy — paint cartridges are expensive!

**Note: Some Python 2/3 solutions may require PyPy to pass.**

#### Constraints

#### Input Specification

The first line will contain two integers and , the number of columns and rows of cells in the image, respectively.

The next lines will each contain characters, each of which is one of the eight characters `.`

, `R`

, `O`

, `Y`

, `G`

, `U`

, `P`

, or `B`

. The character on the line represents the required color of the cell on the row.

#### Output Specification

Output the minimum number of red, yellow, and blue paint cartridges Minestro needs to buy to paint the picture, separated by spaces.

#### Sample Input 1

```
6 4
..RR.P
..OORO
BBB.UU
ROBB..

#### Explanation for Sample Output 1

Minestro needs red cartridges: for the first row and in every other row. He needs yellow cartridges: in the second row and each in the last two rows. blue cartridges are used: in the first row, in the third, and in the last.

#### Sample Input 2

```

#### Explanation for Sample Output 2

Minestro needs:

- red cartridges: in the first row, in the fifth, in the sixth, in the seventh, and in the eighth row.
- yellow cartridges: in the first row, in the second and third each, in the fourth and fifth each, in the sixth and seventh each, and cartridge each for the last two rows.
- blue cartridges: in the first row, in the fifth, and in the sixth row.
