Problem type

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 $H$ ~H~ hunger points. If he eats $A$ ~A~ apples, he will gain at most $\min(H, A)$ ~\min(H, A)~ hunger points since he only has at most $H$ ~H~ hunger points.

To further this visualization, Bob will lose $1$ ~1~ hunger point every second.

He cannot have negative hunger points.

Initially, he has $0$ ~0~ hunger points when he eats the apples.

After eating the $A$ ~A~ apples instantly, he will wait $S$ ~S~ seconds and wants to know the state of his hunger bar.

Can you help him determine his remaining hunger points?
