OP solved it with built-in methods, closing

• @LaurentBouvier - You are mixing up n and m, in (2,1), there are 3 points on a line, and 2 more on the arc.
• @sadegh-moayedizadeh - You are ignoring the 2 points on the edges of the diameter and arc (A and B)

You're welcome :)

I didn't know that!
Thank you so much :)
That is very helpful.

Do you know you can print the input? https://docs.codewars.com/training/troubleshooting/#print-input

Please provide more details about test cases in errors, specially with edge cases.
When displaying erros while attempting a submission please include the input of the test case.

An issue is a bug in the kata, not a problem with your code. Please read carefully the description. And if you still don't get it, this Discourse page is full of people asking the same.

I am trying to solve this kata with javascript. The is the only case which is failing, pls suggest why this error
expected [ 0, 0 ] to deeply equal []

Thanks so much

but when i return empty it wants [0,0] and when i return [0,0] it wants empty

@rowcased when my code outputs [0,0] it says that it should equal [] but when i output [] it says that it should equal [0,0]

The Maybe monad in Haskell can be baffling. Don't focus on the Int / Integer question here, the problem is Maybe needs to be handled in a special way. I cannot see how I could help you without giving away the solution, sorry, but I hope you will find some helpful informations there: https://wiki.haskell.org/Maybe

I'm new to haskell. I get this error:

Couldn't match expected type ‘[Integer]’
                  with actual type ‘Maybe [Int]’

Can anybody give me a hint?

you could inherit "int" and avoid all that

i liked that system of a down reference
