## Barbecue Skewers
|
||
|
|
|
||
|
|
You are in charge of the barbecue grill. A **vegetarian skewer** is a skewer that has **only vegetables (-o)**. A **non-vegetarian skewer** is a skewer with **at least one piece of meat (-x)**.
|
||
|
|
|
||
|
|
For example, the grill below has **4 non-vegetarian skewers** and **1 vegetarian skewer** (the one in the middle).
|
||
|
|
|
||
|
|
```text
|
||
|
|
["--xo--x--ox--",
|
||
|
|
"--xx--x--xx--",
|
||
|
|
"--oo--o--oo--", <<< vegetarian skewer
|
||
|
|
"--xx--x--ox--",
|
||
|
|
"--xx--x--ox--"]
|
||
|
|
```
|
||
|
|
|
||
|
|
#### Examples
|
||
|
|
|
||
|
|
Given a BBQ grill, write a function that returns `[# vegetarian skewers, # non-vegetarian skewers]`. For example above, the function should return `[1, 4]`.
