Answer 1

Katana 2.0 ,

Not clear what you are asking for. Can you please rework your question:

> Which programming language you are talking about
> Give some more details what the input is and what you expect as output

Answer 2

I think I understand the less then half question....

for (iterator, condition, increment/decrement) { body }
while condition { body, increment/decrement }

be very careful! you can easily code an infinite while loop!

I hope this helps
