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
18 -18 10 0 -7
-20 0 17 29 -26
14 20 27 4 19
-14 12 -29 25 28
Note: the numbers generated in your program will not match the sample output, as they will be randomly generated.
