This is a Kotlin program that solves the popular word game Scrabble. Given a set of tiles with letters on them, the program finds all valid words that can be created using those tiles.
To use this program, simply run it from the command line with a list of tiles as arguments. For example:
$ kotlin ScrabbleSolver.kt A B C D E F G
This will find all valid words that can be created using the letters A, B, C, D, E, F, and G.
