Kleinberg, Jon. Algorithm Design $($p$.191,$ q$.7)$ Now let each job consist of two durations. Ajob i must be preprocessed for pi time on a supercomputer, and then finished for fi time on astandard PC$.$ There are enough PCs available to run all jobs at the same time, but there is only onesupercomputer $($which can only run a single job at a time$).$ The completion time of a schedule isdefined as the earliest time when all jobs are done running on both the supercomputer and the PCs$.$Give a polynomial time algorithm that finds a schedule with the earliest completion time possible.
