Notes:
[*1] Can you see why the loop steps by two? If not, then count how
many stars there are in each row of the diamond.
[*2] Note the difference between print() and println().
If you really cannot understand the program, then work through it on
paper, keeping track of all the variables by hand. That will give you
more insight into how it does its work.
