Processes 0-4 are related as follows: 1, 2, 3 are children of 0, and 4 is a child of 2. Assume that the Process Control Blocks (PCB8) are implemented as an array indexed by the process number Each PCB has the links: parent (p), first child (c), younger sibling (ys), and older sibling (os) Use the following table format to represent the PCB array Process ID 0 1 2 3 4 5 Other Stuff p C ys OS (a) Complete the PCB array to include the values of the 4 links for all processes, to reflect the parent-child hierarchy as described in Section 2.2 (b) Modify the PCB array to reflect the creation of a new child, 5, of Process 2.
