In general, the code is clear, for each element of the array of 3, the conditions for obtaining them are separated by commas, for 1 number it is just the number itself (for 2 and 3 according to the formula, (or 2 times 15))

hard to read :(( but speed didn't chande... right?

How it works?

Clever, but unreadable.

Yeah, people need to learn the difference between unnecessarily complicated code that they think it looks cool and best practices

Are you looping through vowels instead of string(a) with just replacing the desired chars ???

this is painful

string.split() already returns an array(list)....

nvm

how did you come up with that algorithm?

Best practice - really?

Shorter code but is it cleaner? If I found this code in the wild I would have to think a long time about edge cases.

clever

runs 2 times through both the strings. One can do better... ;)

@anter check the link too, if you want a way to totally avoid the use of if/else ;)
