In another Kata I came across a weird `sort` function to implement. We had to sort characters as usual ( 'A' before 'Z' and 'Z' before 'a' ) except that the `numbers` had to be sorted **after** the `letters` ( '0' after 'z') !!!

(After a couple of hours trying to solve this unusual-sorting-kata I discovered final tests used **usual** sort (digits  **before** letters :-)

So, the `unusualSort/unusual_sort` function you'll have to code will sort `letters` as usual, but will put `digits` (or one-digit-long `numbers` ) **after** `letters`.

## Examples
```python
unusual_sort(["a","z","b"])  # -> ["a","b","z"]  as usual
unusual_sort(["a","Z","B"])  # -> ["B","Z","a"]  as usual

//... but ...
unusual_sort(["1","z","a"])  # -> ["a","z","1"]
unusual_sort(["1","Z","a"])  # -> ["Z","a","1"]
unusual_sort([3,2,1"a","z","b"])  # -> ["a","b","z",1,2,3]
unusual_sort([3,"2",1,"a","c","b"])  # -> ["a","b","c",1,"2",3]
```
**Note**: `digits` will be sorted **after** "`same-digit-numbers`", eg: `1` is before `"1"`, `"2"` after `2`.
```python
unusual_sort([3,"2",1,"1","3",2])  # -> [1,"1",2,"2",3,"3"]
```

You may assume that **argument** will always be an `array/list` of **characters** or **one-digit-long numbers**.
