Yeah, forgot to mention the completions on Dart XD.

The number of completions 74 out of 15,733 that you are seeing is:

your_language out of all_completions_in_all_available_languages

So for example there are 4741 completions in Python as I just looked now, whereas there are only 74+1 brave Dart enjoyers ;)

74 completions out of 15,733 (with me it is now 75)... Just impossible!

never mind I got it lol

I couldn't quite get something that wan't a Lambda working, so I settled for organizing the existing code.

Oh come on! I misunderstood what was expected from me! If only you showed the way the S-odd and S-even were supposed to be concatenated. I just made S-odd + S-even, cause of my understanding of this kata instructions.

(Not urgent)

I solved this kata on JS and something confused me. So at last I pressed the test button (same was on attempt button), it said that I fully solved the kata, but the output side was totally red, as if I actually did not solve it or gave wrong outputs. I don't mind that it is bad, but for a good view this could probably be fixed, right?

Checking by charCode is clever. Didn't come to mind that quickly, that I could use this.

Gotta learn the regular expressions for real... i feel it is time to

Really, it took me 10 minutes only to realize what does the input m stand for.

You can always look for methods used in solutions on web. It is not a problem. From aside these solutions might seem easy to write, but when it comes to practice, it is not that easy to remember which method is the best for a particular case. Practice, however, will solve that problem :)

If I just do nothing and return 0 it will already take ~5000 ms time to complete... why is it taking so long?
