Most languages have a `split` function that lets you turn a string like `“hello world”` into an array like`[“hello”, “world”]`. But what if we don't want to lose the separator? Something like `[“hello”, “ world”]`.

#### Task:

Your job is to implement a function, (`split_without_loss` in Ruby/Crystal, and `splitWithoutLoss` in JavaScript/CoffeeScript), that takes two arguments, `str` (`s` in Python), and `split_p`, and returns the string, split by `split_p`, but with the separator intact. There will be one '|' marker in `split_p`. `str` or `s` will never have a '|' in it. All the text before the marker is moved to the first string of the split, while all the text that is after it is moved to the second one. **Empty strings must be removed from the output, and the input should NOT be modified.**

When tests such as `(str = "aaaa", split_p = "|aa")` are entered, do not split the string on overlapping regions. For this example, return `["aa", "aa"]`, not `["aa", "aa", "aa"]`.

#### Examples (see example test cases for more):

```python
split_without_loss("hello world!", " |") #=> ["hello ", "world!"]
split_without_loss("hello world!", "o|rl") #=> ["hello wo", "rld!"]
split_without_loss("hello world!", "h|ello world!") #=> ["h", "ello world!"]
split_without_loss("hello world! hello world!", " |")
                  #=> ["hello ", "world! ", "hello ", "world!"]
split_without_loss("hello world! hello world!", "o|rl")
                  #=> ["hello wo", "rld! hello wo", "rld!"]
split_without_loss("hello  hello  hello", " | ")
                  #=> ["hello ", " hello ", " hello"]
split_without_loss(" hello world", " |")
                  #=> [" ", "hello ", "world"]
split_without_loss("  hello hello hello", " |")
                  #=> [" ", " ", "hello ", "hello ", "hello"]
split_without_loss("  hello hello hello  ", " |")
                  #=> [" ", " ", "hello ", "hello ", "hello ", " "]
split_without_loss("  hello hello hello", "| ")
                  #=> [" ", " hello", " hello", " hello"]
```
