Hi,

I'm trying to write a function that will check my stack values.
If any value appears twice (or more), than the function should return false. Otherwise it will return true.

I don't know where to start..

Thanks in advanced :)

Hint: nor do we.

What is this 'stack'? Is that a class you've implemented, or are you talking about the runtime stack? Or possibly java.util.Stack?

Urgh, the docs for java.util.Stack leak implementation details.
