Detailed Instructions on Processes Layout (14 points): 1) Write a program to answer this problem using only one process. 2) Write a program to answer this problem using multiple processes where each process spawns at most one process. (Like DFS). 3) Write a program to answer this problem using multiple processes where the first process spawns a fixed number of processes, say X, and they (the children) spawn their own X multiple processes each, and so on and so forth. 4) Ensure that in all cases you are using the appropriate system calls for InterProcess Communication (IPC) and for making the processes collaborate harmoniously, terminate gracefully, and without zombies 5) Your ultimate goal should be to produce such a hierarchy of processes (process tree) that produces the final result faster. Can you fine-tune the size of variable X to do that? Or are the preceding configurations the clear winners? Consider lists of increasing sizes. 6) Can you create an arbitrary number of processes or are there any limitations? If you find limitations in your version of Linux OS, please show (e. g. via a printscreen or a file) what are your exact limitations in increasing the number of processes you will be generating. Why is this so?
