Fixed.

P.S. Your solution works with NATONAREPOTENETOPERANOTAN ->

NATON
AREPO
TENET
OPERA
NOTAN

but fails with squares like 'XXXJXXJERXXXJGXS'

@Darshan97, the possible duplicate that you refer to never
considers the "name" to be a null name, or the string to
search for the name in to be a null string. Of course,
it is meaningless in the context of that kata.

However, subseq tests for those conditions as well.

Therefore, please remove your objection, and move this problem
out of beta.

21, 20 //consecutive
22, 40
39, -56
30, -55
95, 94 //consecutive

That's how you separate the input in pairs

I guess I'm a bit dumber cause I still see three pairs. Could anyone throw me a bone??

Just realized the other one is Javascript only

Whoops! you're right

i think there's no such cases ..

Duplicate issue.

Added 100 random tests for C# and Python, does the test suffice?

Yes, but there is a significant difference... let me not point that out...

4*(ik), but in a weird way (look at doc's message)

Check the kata now
