Write a program that asks the user to enter three integer values. The program should then use three threads to perform the following calculations: Thread 1: Calculate the maximum value of the three integers. Thread 2: Calculate the minimum value of the three integers. Thread 3: Calculate the average value of the three integers. After all the three threads have completed their calculations, the program should display the results in the main thread. Your program should use POSIX threads and should not use the pthread_exit() function or the pthread_cancel() function..
