Playing a bit around this article: https://sandimetz.com/blog/2016/6/9/make-everything-the-same
Which I stumble upon from gabrielbarker/unconditional.
It is interesting to notice how I created one of the worst solution possible, maybe because I didn't want to use conditional but was only thinking with it anyway.
I forgot to think out of the box. 😅
For S. Metz's solution, see: https://github.com/skmetz/play/blob/master/roman_numerals/roman_numerals_medium.rb
So my opinion on the different approaches would be something like:
| Solution | S. Metz | A. Baumann (3c3a31c) | 1 (1f2189f) | 2 (8b61664) | 3 (5aa1e0f) |
|---|---|---|---|---|---|
| Complexity / Readability | High | Low | Medium | Medium | Medium |
| Speed (supposed) | Medium | High | Low | Low | Low |
| Memory (supposed) | High | Low | Low | Low | Low |
Conclusion: for this one problem, the specific code that S. Metz despises is the best fit, IMHO.
