I always thought that my old friend John was rather richer than he looked, but I never knew exactly how much money he actually had. One day (as I was plying him with questions) he said:

* "Imagine I have between `m` and `n` Zloty..." (or did he say Quetzal? I can't remember!)
* "If I were to buy **9** cars costing `c` each, I'd only have 1 Zloty (or was it Meticals?) left."
* "And if I were to buy **7** boats at `b` each, I'd only have 2 Ringglets (or was it Zloty?) left."

Could you tell me in each possible case:

1. how much money `f` he could possibly have ?
2. the cost `c` of a car?
3. the cost `b` of a boat?

So, I will have a better idea about his fortune. Note that if `m-n` is big enough, you might have a lot of possible answers. 

Each answer should be given as `["M: f", "B: b", "C: c"]` and all the answers as `[ ["M: f", "B: b", "C: c"], ... ]`. "M" stands for money, "B" for boats, "C" for cars.

**Note:** `m, n, f, b, c` are positive integers, where `0 <= m <= n` or `m >= n >= 0`. `m` and `n` are inclusive.


## Examples:
```
howmuch(1, 100)      => [["M: 37", "B: 5", "C: 4"], ["M: 100", "B: 14", "C: 11"]]
howmuch(1000, 1100)  => [["M: 1045", "B: 149", "C: 116"]]
howmuch(10000, 9950) => [["M: 9991", "B: 1427", "C: 1110"]]
howmuch(0, 200)      => [["M: 37", "B: 5", "C: 4"], ["M: 100", "B: 14", "C: 11"], ["M: 163", "B: 23", "C: 18"]]
```

Explanation of the results for `howmuch(1, 100)`:

* In the first answer his possible fortune is **37**:
 * so he can buy 7 boats each worth 5: `37 - 7 * 5 = 2`
 * or he can buy 9 cars worth 4 each: `37 - 9 * 4 = 1`
* The second possible answer is **100**:
 * he can buy 7 boats each worth 14: `100 - 7 * 14 = 2`
 * or he can buy 9 cars worth 11: `100 - 9 * 11 = 1`
