Good question

Stephan Allgeier on 10 Jan 2020

I really like this problem. So far, this is the one I had to think about most. Mostly because the straight-forward recursive implementation is simply not feasible for longer inputs.

Apparently the test suite needs to be augmented!

Ned Gulley on 12 Mar 2013

Done. People never get tired of look-up tables.

David Verrelli on 21 Apr 2018

Indeed: all of the current supposedly 'top ten' submissions here (by Cody-size) are hard-coded hacks! The Test Suite can be augmented by: (i) adding more arbitrary test cases; (ii) adding test cases in which the first [and last] characters/words are the same as in some other test case(s); (iii) banning mention of numbers that correspond to results and need not be mentioned in legitimate submissions (e.g. 18, 25, 27) [as implemented for Problem 44466]; and (iv) potentially banning other key words appearing in other 'generic' hacks (per Solutions 312146 and 1039520). —DIV
