not so much guessing, but perhaps extrapolating or deducing...

but anyway, if you've learned about numbers a bit, and you stare at the sample tests critically enough, the formula just leaps out at you

Never written a solver for this before, the answer is just obvious from the sample tests imo.

how is it a spiral even in the instructions?

Thanks for the Kata! Had a lot of fun discovering Go with it :)

Easy yet good to know.

Python new test frame work

What's considered a 3kyu has really changed over time.

I'm confused, can anyone explain how the examples given look like spirals

Отличный ката. Огромное спасибо автору.

it becomes easy when u nderstand how to fill 2 dimentional array

Great kata, thank you. Definitely helped having done Snail first (https://www.codewars.com/kata/521c2db8ddc89b9b7a0000c1/javascript).

Great challenge! I recommend checking a similar, but easier kata at first: https://www.codewars.com/kata/536a155256eb459b8700077e
That would give you a good basis for solving this one.

In JavaScript, I ran into the following error when attempting to test:

"assertSimilar is deprecated, use assert.deepEqual"
