Time to wrap up this S&SMC#23.

Thanks for these painstakingly detailed notes about your solutions; these are always enjoyable even I've not had time, or sometimes the skills, to tackle them. I particularly like your use of "Lessons learned" to highlight the key techniques used for each solution, this helps a lot to drive these points in.

I had no idea one could apply the substring operator (I like 'slicer' better) multiple times. Though it appears to not be documented it does make sense following the 71b's syntax, etc. Very clever!

Thanks for another set of interesting and educational challenges. I suspect all the drama taking place in parallel distracted folks from playing along.
