'substring' call should be replaced with 'dropLast' call

Reports calls like s.substring(0, s.length - x) that can be replaced with s.dropLast(x).

Using corresponding functions makes your code simpler.

The quick-fix replaces the substring call with dropLast.


fun foo(s: String) { s.substring(0, s.length - 5) }

After the quick-fix is applied:

fun foo(s: String) { s.dropLast(5) }
