Given a set of 7 job requests, (si, fi, bi), defining the start times, finish times, and benefits of each job: 1:(1, 2, 6), 2:(1, 3, 8), 3:(2, 4, 5), 4:(3, 5, 6), 5:(4, 6, 9), 6:(6, 9, 7), 7:(7, 9, 3) Note that the jobs area already ordered by end time (and by start time within same end time). Using dynamic programming, solve the job scheduling problem for this set of job requests. Show the predecessor array and the benefits array. Then give the jobs that would be included in the optimal solution, and the total benefit. (15 pts)
