No, the reason is because you only halt the loop when s == m, but what if s > m and there are still millions of iterations to go?

OP solved it, closing

draw the movement in a paper.. it basically move all the way and returned to the same position.. then the last movement was towards "West"..

?

a should output ['NORTH','WEST']

have you modified the first test case in the sample tests?

there is a missing 'SOUTH' in the third index

hmm no

this has nothing to do with linked lists. but either way there's no pre-existing linked list class, so you'll just have to create one yourself for this kata ;)

but you gotta tell us what to do clearly.

Thanks for your suggestion, but no, I don't gotta. I am not going the make this one of those Kata where every formula is spoon fed so the poor monkey can just assign the variables to arrive at the solution.

... calculating the volume of the blob(which is probably a sphere)

Why "probably"? The Kata description literally says: "I hava the bigga spherical blob of dough."

Yes, it does.

After 'z' comes 'a'.

Hello, kindly explain what you mean by, "The alphabet wraps?"
