Read this and see if you get it.

the creative comment was a sarcastic one

on topic:

if you read that tutorial, you should get all you need, basically break the problem down into smaller problems:

• How to get the string backwards (ie taking each character from the end backwards)
  
• Putting the string together
  
• Displaying it
  
• Finding the vowels
  
• Exceptions on unexpected input
  
• Putting the string together
  
• Display
  

Learning to problem solve is a major thing to learn for programming (and many other things, this is why someone who is good at math can generally be a good programmer, math students are typically the better problem solvers)
