Operating Systems Question 16 A commuter plane has seats for 19 passengers and a single narrow door that can only accommodate one passenger at a time. Complete the following solution in a way that avoids deadlocks. semaphore seats = 19: semaphore mutex = 1; debark(/ P(&mutex): go_through narrow door0: V(&mutex): V(&seats): } // debark embark(X [A]: [BI: go_through narrow door0: [C: } // embark
