Analysis of Pseudocode Sempahore Solution, Operating System

Assignment Help:
Gopher Gallery consists of a shopping mall and a cart ride that covers the 150 acre habitat. There are m visitors and n single-person vehicles. Visitors stroll around the mall at their leisure, then line up for the cart ride. When a cart is
available, it allows the single passenger to climb aboard and drives around the habitat for a random amount of time. If the n carts are all taken, then a future rider waits; if a vehicle is available but no one is waiting, then the vehicle waits.
The solution to this problem must synchronize visitor tasks and vehicle tasks using semaphores.
Below is a potential solution. Correct any issues with this code, if any exist.
Explain your position in detail.

Semaphore vehicleAvailable = 0, vehicleTaken = 0, vehicleFilled = 0, visitorReleased = 0;

Visitor()

{
vehicleAvailable.wait();
vehicleTaken.signal();
vehicleFilled.wait();
visitorReleased.wait();

}

Vehicle()

{
while(True)
{

vehicleAvailable.signal();
vehicleTaken.wait();
vehicleFilled.signal();
Drive through habitat for some arbitrary amount of time;
visitorReleased.signal();

}
}
