Suggestion of a different solution to Matrix

[ramiloif]

Maybe my solution will be a little easier to understand .
My solution uses the fact that we moving on the same pattern :
right -> down -> left -> up -> (->right ->....)
I created a location object in order to simplify the movement action ;
the object have row and col properties .
we are starting with location = {row:0, col:0}
Each direction can be easily translated to a similar object that represents a step:

const right = {row: 0, col:1};
const down = {row:1, col:0};
const left = {row :0, col:-1};
const up  = {row : -1 , col: 0};

The last part is to create an empty matrix fill it with 0 ( or null or whatever not in our numbers range )

now all left is to use counter until it gets to n*n
fill the location and move to the next legal location .
if the next location is not legal or we already been there ? we just change the direction to the next one in a cyclic way :)
