The board of trustees has decided to install a number of lounges across campus for students and teachers alike to sit and relax in. The use of these lounges, however, is governed by a few rules: . A lounge may be occupied solely by students or teachers - they may not intermingle! A maximum of 10 students may occupy a lounge at a time A maximum of 5 teachers (we're a little more stressed, see) may occupy a lounge at a time students keep arriving to enter, teachers can't be kept out forever . No single group may hog the lounge forever; i.e., if students currently occupy the lounge and For this problem you are to implement the code for the two types of threads that will be executed by individual students and teachers. All synchronization should be performed using the following variable definitions: loungeEmpty Semaphore (1) turnstile =Semaphore (1) student-mtx = Semaphore (1) teacher-mtx semaphore (1) student_multiplex Semaphore (10) teacher_multiplex - Semaphore(5) students = 0 teachers0 You should NOT introduce any other variables in your solution. Clearly indicate the separate threads and where each is free to "lounge". Use the empty space below or the following page for your solution.
