Created By: Geoffrey Challen
/ Version: 2022.7.0

Complete a method named arrayFill3Pattern that creates Int arrays filled with a 3-based pattern. Here are some examples:

1 4 7
4 7 10
1 4
4 7
7 10
10 13

And so on.

Your method should accept two int parameters: the number of rows and columns in the array. Both values will be positive. Return a two-dimensional Int array (Array<IntArray>) with the first index the rows and the second the column filled with the pattern as shown above.
