Compute the worst case response times produced by Rate Monotonic for the
sporadic tasks illustrated below, where areas in light grey represent non-preemptive
regions of code, whereas regions in dark grey are fully preemptable. The num-
ber inside a region denotes the worst-case execution time (WCET) of that por-
tion of code, whereas the number on the right represents the WCET of the
entire task.
