Hi! How do I replace last space in sting: `one two three` -&gt; `one two\nthree`.

There's `replaceFirst`, but no `replaceLast`

```
val idx = string.lastIndexOf(' ')
val replaced = if (idx &lt; 0) string else string.replaceRange(idx, idx+1, "\n")
```

Although there should be a `replaceLast` for sure. Not sure why there isn't.

Thanks! I have just done the same :slightly_smiling_face:

Unless your string is huge, the braindead version also works OK: `string.reversed().replaceFirst(" ", "\n").reversed()`…
