I personally don't know anything about hash tables and sadly wouldn't know where to start
That's why you would need to type /help hash tables to learn about them, or check this small first step
hash table tutorial. It doesn't cover everything about hash tables, but certainly enough to make your script. I basically already gave you the script, just not in code but in words. Anyway, if you don't want to learn about them, that's fine, I'm sure someone will whip up the code for you. I just thought this would be an excellent incentive to learn about hash tables and improve your skill a bit
I like this quote a lot:
Give a man a fish, you have fed him for today. Teach a man to fish, and you have fed him for a lifetime.
