Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.

good for you man, im still timing out from using the backtracking approach :(
EDIT: I'm sorry, i used some code on github for the solution. Before anyone says anything, I probably shouldn't have done that, however I have spent some time reading the code, and I can fully understand it now. I think the point of codewars is to learn, but sometimes give up if it is too difficult. And for the reason why I did that, well, it's late now, so I got frustrated and just copy pasted some code off the internet.
This was a very challenging and fun kata! It required a lot of thought about which data structure and which algorithm to use to minimize the number of computations. In the end it was worth it and I managed to pass it marginally.
well, this one is insane
A correctly composed Sudoku must have a unique solution !
timing out from backtrack :(
js plz
Its 5 per test.
How many assertions per test? In my 100 random tests I've got 255 assertions passed but still timing out.
because that's a code working only for python 2
This code doesn't seem to pass when I copy and paste it.
range(1, 6) should equal [1, 2, 3, 4, 5]
?

У меня без list(...) не получилось, но это круто что у тебя так получилось
lol why was this downvoted
woah that's just amazing. I never fail to learn new things even in 8 kyu katas
Very interest Kata :) Thank you
luckily i found the right method. my algorithm solved everything in 6 seconds, only on one Sudoku from your set it was required to take 1 step back.
also my algorithm solved in 2 seconds "the most difficult sudoku in the world" by taking 14 steps back. I'm glad that my program coped with it!
