Write a method called printGrid that accepts two integers representing a number of rows and columns and prints a grid of integers from 1 to (rows * columns) in column major order. For example, the call

printGrid(4, 6);

should produce the following output:

1 5 9 13 17 21
2 6 10 14 18 22
3 7 11 15 19 23
4 8 12 16 20 24
