Help defining multi-dimensional array

Ruby Team,
I would like to define a 3x3 array of integers.
Can anyone tell me how this is done?
I would like to start playing with Ruby and I want to start by solving Magic
Squares.

Thank you

Ruby Team,
I would like to define a 3x3 array of integers.
Can anyone tell me how this is done?

Here's one way:

>> Array.new(3) { Array.new(3) { 0 } }
=> [[0, 0, 0], [0, 0, 0], [0, 0, 0]]

Hope that helps.
