The input is a set of jobs j1, j2, . . . , jN, each of which takes a one-time unit to complete. Each job ji earns di dollars if it is completed by the time limit ti, but no money if completed after the time limit.
a. Give an O(N2) greedy algorithm to solve the problem.
b. Modify your algorithm to obtain an O(N logN) time-bound. (Hint: The time-bound is due entirely to sort the jobs by money. The rest of the algorithm can be implemented, using the disjoint set data structure, in o(N logN).)

In deadlock avoidance using banker’s algorithm, what would be the consequence(s) of: (i) a process declaring its maximum need as maximum possible for each resource. in other words, if a resource a has 5 instances, then each process declares its maximum need as 5. (ii) a process declaring its minimum needs as maximum needs. for example, a process may need 2-5 instances of resource a. but it declares its maximum need as 2.
