Yeah, that demo problem would probably take me at least several hours to solve. I'm bad with sequences and I have a volatile short term memory which means I make mistakes and am slow to process numbers and logic. Interestingly these flaws cause me abhor any over complex logic or code where you have to remember more than 4 or 5 things at once to use properly, which makes my code clean. So maybe I'm not a good programmer (I can't write the complex stuff very easily) but the code I write is usually good. Try testing for that Codility! BTW 10-20% of the population is like me.
