Converting an array into a single array

I need some help. I'm brand new to codes and I'm learning Ruby right now. I have to turn this array into a single array. Here's the initial array:

array = [["a", "b"], ["c", "d"], ["e", "f"], ["g", "h"], ["i", "j"]]

This is the desired conversion:

["a", "b", "c", "d", "e", "f", "g", "h", "i", "j"]

So far I have this:

index = 0

5.times do p array[index] index = index + 1 end

I know that I have to add a loop, but I can't figure this out for the death of me. Thanks!

I'm not 100% sure on this one. But you try do the following.

array = [["a", "b"], ["c", "d"], ["e", "f"], ["g", "h"], ["i", "j"]]
arr = Array.new
array.each  {|a| array[a].each{|b|arr.push(b)}}

my syntax might be wrong here, so i'll explain it as well.

You could create a new array and iterate over the original array and then iterate over the element arrays "["a","b"]" and push them to the new array.
