I know this is late to the party, but I would much rather read clear and concise solutions over 10-12 lines than an overly complicated one-liner that gives anyone but the author a headache to look at (though this soluion is nice I think, not hating). Solving a problem in 1-3 lines can be cool and elegant, or it can be messy as hell. Case in point is my solution to this task, which passed the tests but is just horrendous and fills me with shame.

Don't worry, it will come.... Solving many more katas from 8kyu and 7kyu to fully understand the basics and learning from the solutions other users provided (the comments are very helpful too), helped me a lot. I'm now somewhat satisfied with some of the solutions I´m providing (only some, but I still hope). Practice, practice, practice :)

Started coding on CodeWars 2days ago and upgraded to 6kyu but I'm not satisfied with my code because after solving the kata's I see the other solutions like this one and I get dissappointed after seeing 1-3 line solutions and comparing them to my 10-15 line solutions.
I try to learn and implement the same coding techniques/functions to optimize my code but it doesn't come naturally/intuitively. But I'll still continue coding, let's see how things turn out to be.
