9.3 Code Practice Instructions
Write a program that creates a 4 x 5 array called numbers. The elements in your array should all be random numbers between -30 and 30, inclusive. Then, print the array as a grid.

For instance, the 2 x 2 array [[1,2],[3,4]] as a grid could be printed as:

1 2
3 4
Sample Output
