Fifteen processes share a critical section implemented by using a binary semaphore named x initialized to 1. Eleven of these processes use the correct code wait(x); critical section; signal(x). However, four processes erroneously use the code signal(x); critical section; signal(x). Assume that each process executes its critical section only once.) Answer the following questions. Calculate the maximum number of processes that can be in the critical section at the same time, and explain your answer. Does your answer change if x is a counting semaphore? Explain.
