"... returns an array of strings containing the coded string in 5 parts ..."

Unless this is intended to be the main difficulty aspect of the kata, it is completely unnecessary and it makes the kata significantly more difficult.

Because opposite directions aren't side by side. Do you end up in the same place? Yes (if the path is plain), but to eliminate them they should be side by side, or after some elimination, become as such, that's a requirement.

Can someone explain to me why the path ["NORTH", "WEST", "SOUTH", "EAST"] is not reducible even though you end up at the same place? That seems to be the point of this kata

Let me work with this pretending ive not read the atrocities written by the outhor

Came back to refresh my memory in python after a long time out and every time i read Find max(abs(length(x) − length(y))) i just got more dumber

I don't know why everyone says this is too easy for a 5kyu challenge. I've completed some 3kyu challenges that were easier than this one💀

omg i feel stupid

umm... why am i asked to put a boolean true or false into a unsigned long long vector
i thought that isn't allowed ???

For 5 testcase in golang i used int(math.Round(sum-priceNew)) for correct round.

I don't understand the description

oh, it was bool() what I was looking for. So simple and I didn't figure it out.

Great practice ! But for advanced use case , consider to use HashMap , so the time complexity will be O(n) for optimizing the performance with large data .
