(50pts) Write a simple sequence-number system through which three conc obtain unique integers in the range , 500]. Use the fork) call to create P, P2, and P3. Given a file, F, containing single number, each process must perform the following steps: urrent processes, P1, P2, and P3, each a a. Open F b. Read the sequence number N from the file c. Close F. d. Output N and the process’ PID (either on screen or test file) e. Increment N by 1 f. Open F g. Write N to F. h, Flush F i. Close F Describe the behavior of your program and explore the reason for this behavior. Provide evidence for your conclusion in form of test-output. You must clearly document your code
