In this question we will look at theInterval schedulingproblem. The problem consists of a set of tasks. Each of these tasks need to be executed in aspecific time interval. Two tasks are set to be compatible if their time intervals do notoverlap. The goal is to find the maximum set of compatible tasks so that as many taskspossible can be executed. For example consider the case of just three tasksTask start time end time Task 1 1 10 Task 2 2 5Task 3 7 9 Here the set consisting of Task 2 and Task 3 is the set consisting of marimum number of compatible tasks. It is maximum because if we select Task 1, then we cannot select either Task 2 or Task 3 as both of them have overlapping intervals with Task 1. Consider a greedy algorithm which always selects the shortest appointment first. Provide an example in tabular form with at least 5 tasks where this algorithm fails. List the order in which the algorithm selects the intervals, and also write down a larger subset of non-overlapping intervals than the subset output by the greedy algorithm.
