I pass all tests but 1 in Scala due to decimals:

Testing: 7.000000000000001E-5
Actual: [14286, 3.1415226550]
Expect: [14286, 3.141522655]

any quick fixes one can recommend?

Hilariously, using memoization and recursively summing factorial(n-1) n times as strings (from summing big numbers as strings kata) doesn't result in time out, it just about does it. I was so surprised that I am here demanding testing solutions more for even bigger values haha

Facing the same issue at this point, I am using recursion and I am passing every case up until 120 or so and then it times out. Did you manage to pass the kata?

I see, thanks for letting me know. I am fairly new to codewars and only now started discovering these inconsistencies, but was pretty sure that the community is aware of this issue for quite some time.

Since there already is a 4kyu kata to Validate NxN sudoku (https://www.codewars.com/kata/540afbe2dc9f615d5e000425) that uses OOP and validates sudoku of arbitrary size, I am really surprised that this is 4 kyu and I see that a lot of others are voicing similar opinions.

Took me hours and several approaches to get the correct logic after starting off completely wrong, but this is a deeply satisfying kata to crack! Thanks a lot.

Great kata, but maybe too easy for 4kyu?

Learnt so much doing this kata, it's awesome.

I am going through the same thing, and I was wondering if tests keep the board from the previous tests with all of my lower case characters and underscores?
I feel like the board should reset itself.
Should this be fixed or should I amend my code? Thanks.
