Suppose that we have a set of activities to schedule among a large number of lecture halls, where any activity can take place in any lecture hall. We wish to schedule all the activities using as few lecture halls as possible. Give an optimal greedy algorithm to determine which activity should use which lecture hall. Justify why your algorithm is optimal.

An algorithm that executes a single instruction in a uniprocessor system is called a serial algorithm. In the case of a multiprocessor computer system, multiple instructions are executed in parallel. A multithreaded algorithm is an algorithm that enables…
