Problem No. 10.3-4. A political campaign is entering its final stage, and polls indicate a very close election.

These estimates are given in the following table in thousands of votes: Area Commercials 1 2 3 0 4 7 0 1 2 3 4 5 Nooo ao oooo O 3 7. 12 14 16 12 15 Use dynamic programming to determine how the five commercials should be distributed among the four areas in order to maximize the estimated number of votes won
