Well, I wouldn't rely too much on the IDE. The danger of this is that it 
leads to a kind of "trial and error" programming: You just write 
something down and then use the debugger to make actual working code out 
of it.

That's not how it should be, especially when you've just started. The 
code reflects your thoughts, so it should at least be logical in itself. 
Sure, we all make mistakes, so there will always be typos, syntax errors 
etc. But when your code is logical incorrect, it shows that you've not 
really thought this through (or maybe didn't even understand the parts 
you've copied and pasted).

This is no critique or something, just a suggestion. In school exams, we 
actually have to write down our code on a piece of paper. This way we 
focus on clear thoughts, not so much on getting the code running 
somehow.

I don't understand the logic, so I can't help you with that. But you 
should structure the cases with nested "if"s.
