I thought having a loop that loops through each command and picking apart the times while comparing the name of the command (e.g. sleep and spawn) might do different things and we can add the times on CPU that way might be easier. Unless I am understanding the problem statement wrong. Thank you for your time.

That approach may work, but the 'picking apart the times' part is difficult because you must account for the interactions and competition between multiple processes. As discussed in Friday's Workshop #5, another (I believe much easier) approach is to loop while there are any processes remaining, having a global clock that advances one usec at a time, and at each instant determining "what is happening now?"
