Need save a path in initial order

crazy!

Uau! This was the hardest kata for me at this moment.

I make a cartesian plane with x and y using a pair, west < x > east and south < y > north. So I make a for across a vector increasing or decreasing the direction . the final result is a value [x,y] , this is a final point. make a regression step by step i have the better way. I passed in the first test , but the other results are confuse.

(If you cannot understand my text , i'm sorry, I am learning english by duolingo)

Well, I maked a exellent code for this kata ( in my opition) , I spend 3 days improving my code for more performance, and yet it cant passed by time out .
I really don't what I must do .

I am not blame if the codewar's computer is not enough fast to run my code ( :-D)

Someone have a hint to help me?
