Write a C program using the fork() system call that generates the Golomb sequence in the child process. The number n will be provided in the command line, where n 1. For example, if n = 4 is provided, the numbers 1, 2, 2, 3 in the Golomb sequence will be output by the child process. Because the parent and child processes have their own copies of the data, it will be necessary for the child process to output the Golomb sequence by calling the user-defined function PrintGolomb(). Have the parent invoke the wait() system call to wait for the child process to complete before exiting the program. Perform necessary error checking to ensure that a positive integer n is passed on the command line. Hint: You may define a function Golomb(n) to return the nth number in the Golomb sequence.

The Golomb sequence is the series of numbers 1, 2, 2, 3, 3, 4,4, 4,.... Specifically, we have 1 234 5 67 8 9 10 11 12 13 14 15 16 nth number 2 23 3444 55 56 6 6 67... Formally, the nth Golomb number, where n 1, 2, 3, ..., is computed by (1) 1 forn 1 f(nin ff(n for n 2 2
