The program has two constraints:

1) Each process can do at most one addition. If you want to calculate the sum of more than two digits, you will have to fork one or more processes in order to do that, and each of the forked processes in turn can process at most one more addition before forking further more process(es) to compute the sum.

2) Each process can fork at most one other process.
