Since Bob has been playing too much Minecraft, he has been viewing everything in terms of Minecraft, including whenever he is hungry.
He visualizes this hunger with a hunger bar with hunger points. If he eats
apples, he will gain at most
hunger points since he only has at most
hunger points.
To further this visualization, Bob will lose hunger point every second.
He cannot have negative hunger points.
Initially, he has hunger points when he eats the apples.
After eating the apples instantly, he will wait
seconds and wants to know the state of his hunger bar.
Can you help him determine his remaining hunger points?
