title: Create Isoceles Triangle using asterisks and only while loops
body: <p>I need to create a triangle of at least 5 rows.</p>
  
  <p>I know how to create the top and bottom but I can't figure out the middle part. I don't know how to find the algorithms to express the changes in spaces added to each subsequent row following the first. Can I get hints? 
  This problem is from my teacher.</p>
