Obviously, nobody that's already in the bathroon gets kicked out, but someone arriving after the sign is up will have to go find another batbroom even if the cleaning hasn't started yet.This algorithm is a solution to a resource access-synchronisation problem: specifically, the controlled resource is the bathroom, and the problem and solution are related to the readers-writers problem. Pseudocode:We can describe this algorithm using two semaphores: a binary semaphore called "mutex" and a counting semaphore called "empty"-When the custodial staff enters the bathroom, they acquire the mutex semaphore to ensure that they have exclusive access…arrow_forwardTo create a dual alternative decision structure, you utilise a(n) statement.arrow_forward
