But isn't it more logical to cancel out everything even if it's not directly opposite? If 'NORTH, WEST, SOUTH, EAST' brings you to the same spot, why does tha kata request to not remove anything (because it's not directly opposite)? I'm just curious, as if I was to build a similar function in the future, I would do it my way

I know, but it's one of the most efficient methods

huh? the person did not use encode, what are you even talking about?

This is easy for beginners like me to understand, and that's all. I think actually solving the problem comes before complexity.

I don't get the joke...

Can anyone explain this? :(

The visualizer only executes the first line of the code...

AMAZING!!! I don't know how people are able to think this way.

;)

You can just create a variable called count which increases by 1 everytime a number is a divisor. This way, you don't have to create an extra list and it's probably faster.

Also, comments are marked with a single #, the second # is unnecessary.
