I don not understand why come here to practice and answer just by using built-in methods.

While that might be true, it does not affect the validity of my statement. This result is not best practice and students should be aware of that fact when seeing all those "Best Practice" buttons being hit.

Originally the translator used camelCase, and it was like that before it was changed. The solver could only change the argument's name.

This is NOT best practice, since it uses camelCase instead of snake_case for the method and argument, which is against the Ruby Style Guide, see rubystyle.guide > Naming Conventions.

I ❤️ Ruby

awesome !!!! :)

This kinda defeats the purpose, but still the right call nonetheless

155+ general obviouses.

i made a mistake what i did was list.map(regexp)

That is clean!

Will this remove trailing spaces on line without markers?

This is awesome. Not reinventing the wheel and nice enough for the eyes.

For some reason, doing this did not work when I attempted it... and only worked once I removed the ampersand.

I'm still not certain how closures work in Ruby... hell, I'm not even certain that is the concept I should be looking up.
