Write a Pthreads program in C on Linux that generates multiple threads. The threads should complete in the order below using semaphores and/or mutex locks. For example, ThreadB cannot complete until ThreadA completes. ThreadE cannot complete until ThreadB and ThreadC completes. The program should display the letter of the thread in it's critical section before exiting. i.e. one ordering would be: A-B-C-E-D-F-G-H. Another would be: A-C-D-B-E-G-F-H. Provide the output for 5 runs. You may need to sleep() each thread random times to vary output. Include output screen shots.

A H G 000 C 0-0-0, B 111/ E
