/prog/ Challenge #42069

Implement a POASTchecker. The POASTchecker will analyse a post number and use heuristic processing to determine whether the number is a /proggles/number, i.e. it will either acknowledge ``dubs'', ``trips'', or ``jackson five GET''. Any reasonable input and output format is allowed.

Good luck!

(defun POASTchecker (x)
(cond
((= (mod (mod x 1000) 111) 0) 'trips)
((= (mod (mod x 100) 11) 0) 'dubs)
((= x 5) 'jackson-five-get)))
