Two Dimensional Arrays in Ruby

Here is a sample program to show you how to declare and use two-dimensional arrays in Ruby programming language. I find Ruby programming language very easy very similar to Python. I enjoy learning Ruby as an alternative programming language to teach computer programming in schools.
