Cause it's very fast solution. But who cares about performance in 2k19 when a fridge has more cores and RAM than my PC. Sarcasm)

who can plz explain this how works

well that looks fabilous but can't understand nothing :/ , first time can't understand code

"WARNING: Segment may contain billion elements, to pass this kata, your solution cannot iterate through all numbers in the segment!"
the point of this kata is to come up with an idea how to calculate the result very fast without even going through the sequence and it requires making some observations about binary numbers

good luck! =]

ok I'm stack with this even my code works well

Process was terminated. It took longer than 12000ms to complete

Sometimes it pays to try unconventional approaches. This kata cries out for a graph-based solution, but this approach came to me when I considered trying them.

Glad you enjoyed it. Happy coding! :)

Edit: Wanted to share that I feel developers too often settle for their first working solution. This first working solution is often overly complex. They settle for this rather than refining it into something of beauty and elegance.

my solution took me 3 days :o i'm so frustrated after seeing how simple is :/

so complicated

so clever man hahaha

ugly code i'm wonder why ppl upvote to clever

your solution must be top one

yeah that's what i've done , pfff was stupid mistake took me lot of time to solve it :/

Your grammar is slightly wrong.

Change "no ones like this" to "no one likes this"
Change "likes" to "like"
Change "like this" to "others like this" in the statement "Alex, Jacob and 2 like this"

0 people = "likes"
1 person = "likes"
> 1 person = "like"

Make sure you read the output box properly.
