- Assume that turn is a boolean array of size 2. All elements are initialized to false. - Assume that the main function creates two threads to execute the function shown above. Assume that it passes the argument 0 to the first thread and 1 to the second thread. - Assume that critical_region() is a function that contains code that accesses shared data and hence needs to be protected via mutual exclusion. - Assume that non_critical_region() is a function that contains code that does not access any shared data or resources. Complete the following sentences based on your observations of the code in updateFunction: - The above thread function the basic requirement of mutual exclusion. - The function the requirement that a thread not in its critical region must not prevent other threads from entering their critical region. - The function busy waiting
