So, I just ran some code in 7.12... it worked, but I don't think it should've.
It wants you to puts each element of each array, but not the arrays themselves.
s = [["ham", "swiss"], ["turkey", "cheddar"], ["roast beef", "gruyere"]] s.each do |sub_array| puts sub_array end
And it accepted that.
But I was just entering that to see what happened. I thought the correct code was going to require another ".each" somewhere... But it took that. Can someone explain this to me?
