I have a grid with keys
grid.keys
=> [[1, 2], [0, 0], [3, 3], [2, 1], [1, 1], [0, 3], [3, 2], [2, 0], [1,
0], [0, 2], [3, 1], [2, 3], [4, 3], [3, 0], [2, 2], [1, 3], [0, 1], [6,
3]]
I need to create a list list of all possible combinations. I would start
by taking the first item, then linking it with every other item, then
truncate the first item, and repeat.
My problem is that on
grid.keys[0].to_s
=> "12"
it mashes the [1, 2] together making it unusable.
Could you suggest a better data structure for storing a list of all
possible combinations?
Linking a hash [1, 2] to [0, 0] and then [1, 1] would simply override
the previous link.
