Hey guys, Can I do something like this with when expresion?

```val arrayNumber = arrayOf(0, 1, 2, 3)

if (arrayNumber.contains(0)) {
    //DO SOMETHING FOR CASE 0
}

if (arrayNumber.contains(1)) {
    //DO SOMETHING FOR CASE 1
}

if (arrayNumber.contains(2)) {
    //DO SOMETHING FOR CASE 2
}

if (arrayNumber.contains(3)) {
    //DO SOMETHING FOR CASE 3
}```
Thanks in advance!

I'd use the `in` keyword instead: `0 in arrayNumber`

Hey,
you could write something like this
```when {
  0 in arrayNumber -&gt; DO X
  1 in arrayNumber -&gt; DO Y
...
}```

It's inclusive when mets more than 1 case?

Also, the `when` and its clauses are like `else if`. Since your `arrayNumber` can have both a 0 and a 1 (and others), using a `when` will change the behavior of your code

Okey that answer my question, Thanks you so much guys!! &lt;3
