Write a program using the fork () system call that prints the given number of Fibonacci sequence (https://en.wikipedia.org/wiki/Fibonacci_number). This input number has to be at least 2. For example, if the input number is 6, it prints 1 1 2 3 5 8. The input integer will be provided in the command line. Because the parent and child processes have their own copies of the data it will be necessary for the child to output the Fibonacci sequence. Have the parent invoke the wait () call to wait for the child process to complete before exiting the program. Perform necessary error checking to ensure that the input integer is 2 or higher is passed in the command line
