You just taught me how to use reduce, thank you!

Haha, same

Same. I also overcomplicated it

How did you pass it if you are not getting the uppercase letters in final string?

wow all same idea :P plus all variables as well

Even shorter than mine, nice one! :)

Agreed, I first solved it in Python and while I am fluent with most of the string methods after years of Python, I had forgotten about this one in absence of practice and solved it with less advanced features and alorithmic logic. Built-in methods are just masked hardwork of creators, and they can indeed be less efficient in cases and you would needa use your own logic!

Damn it! lmao I didn't know that method exists, Nice!! I'm going to add this to my future references thank you very much!

good though

For those who did not resolve it that way... At the end of the day those like us who resolved this challenge with an actual algorithm, are the ones who create built-in methods. Actually built-in functions are just a mask hiding a larger code and guess what... Built-in methods might be much more unefficient than a customized algorithm...

Less lines of code does not mean good code

To make myself feel better I'd say, those of us who actually wrote an algorithm are geniuses too, instead of using built-in functions. :P

RIGHT!!! I thought I had finally found the most basic way to the solution with a ternary operator. But that good ole 'truthy' statement....lol

Wow, how can I forget something so basic... And here I thought using RegEx was being clever of me 😂

I think this solution is not what a beginner would provide
