2 dimensional array to single arrays

[John Butler]

Hi,

I have a nasty loop which creates 2 single arrays from a 2 dimensional
array,

is there a quicker way to do it?

[["a",1],["b",2],["c",3]]

So i want an array
["a","b","c"]

and

[1,2,3]

Any quick method to do this?

my_array = [["a",1],["b",2],["c",3]]

letters = my_array.collect {|array| array[0]}
numbers = my_array.collect {|array| array[1]}
