smart to use another var to store pos i am 95% close to this one

Oh come on! I solved this in 59 lines of code, ternary operators, a ***** recursion and a bunch of if statements and spend an hour only to see this?

good job tho.

Nice solution

My god, wonderful solution! Thanks!

nice

Love it! Best practice no doubt!

Well,one cannot make everyone happy. If you are into creating such a sequence good luck doing it. I don't see a reason this is bad. My initial intention was to create a kata for the ones who know about ubbi-dubbi, and provide some fun experience.

I hate to be geeky, but the description says "The rules are simple everytime you see "a" or "e" or "i" or "o" or "u" in a word just prefix it with "ub"." No word about uppercase.

Hey, we could make a series!

• kata #1: replace as with bs
• kata #2: replace bs with cs
• kata #3: replace cs with ds
• ...
  Let`s get started! :-)

There're already many katas asking to do simple text replacements (this lata, "pig latin" etc.).

Sure, but then the description should be more clear.

It seems you only have to replace lowercase letters (seeing the expected results).
