$4\mathrm{.}1\mathrm{.}5$: Handling input exceptions: restaurant max occupancy tracker.

I. Full screen

Arrange the following lines to make a program that determines when the number of people in a restaurant equals or exceeds $10$ occupants. The program continually gets the number of people entering or leaving the restaurant. Ex: $2$ means two people entered, and $-3$ means three people left. After each input, the program outputs the number of people in the restaurant. Once the number of people in the restaurant equals or exceeds $10,$ the program exits.

If an InputMismatchException exception occurs, the program should get and discard a single string from input. Ex: The input $"2$ abc $8"$ should result in $10$ occupants. Not all lines are used in the solution.
