While "his" code tries kind of CSV handling (splitting on comma) his "data" doesn't have comma separation.

I'd say he C&P-ed googled codeš to pretend own efforts! :-|

Hmm, I don't think that's the case; he just didn't share his actual input data. I actually began coding a "clean" solution that he'd be able to use as a starting point, but stopped when I realized that there was no sample data to be found to test it against. Trying to reverse-engineer what it might look like would've been error-prone, and besides, like any good programmer, I'm lazy. (Which is not to say I'm a good programmer, mind you.)
