We are about to commence OC2 (running a week late) and I have given my students some algorithms to evaluate for revision. On one in particular I realised I made an error of logic when evaluatiing it myself and have now confused my self to point of frustration. It's the one below. It has two count loops which it uses to select data in an array but they both have identical conditions. As I am currently reading it values will never be passed to the second loop as the evaluation condition that ends the first loop will also end the second???? Scratches head......sure I'm failing to see obvious!
