traverse two-dimesional array in ruby

[aidy]

Hi,

I know I can use the each method to traverse a one-dimensional array

my_array.each{|x|
p x
}

but how would I do a similar thing for a two dimensional array?

cheers

Once you have the 'nested each()' trick down, you realize that this
is basically what Array#flatten() does. As long as efficiency isn't
paramount, you can shortcut with 'array.flatten.each {}' for any depth.
