Help with a APCSP sample question


First timer APCSP teaching. My question is repat and repeat while. For and while loops are not used in AP format.

A student ask me to explain an answer, and for the life of me, those google responses are plenty! Some many variations of languages.

Can someone help me break this down in plain English, please?

Thank you and God Bless!

Can you step through the logic. Since you’re toggling the sign for value, and you know that number is a positive int, you really only need to consider two possibilities - number is odd or even. Can you step through the logic if number is 1 and if it is 2?
