Creating an hourglass using asterisks

Question

I would like to create an hourglass using the \"*\" character. For example if the user input was 5 then it would look like this:

*****
 ***
  *
 ***
*****
         


        

Answer 1

Pseudocode:

function stars(n):
  c1 = 0
  c2 = n
  for i = 1 to n
    print ' ' * c1
    print '*' * c2
    if (i < (n+1) / 2):
      c1 ++;
      c2 -=2;
    else:
      c1--
      c2 +=2
    print newline

This should get you close to your answer... now translate into java

** note - this works for odd number. You may need to tweak for even n **
