Greedy activity selector
WebActivity selection problem can be solved by Greedy-Iterative-Activity-Selector Algorithm. The basic idea is to always pick the next activity whose finish time is least among the remaining activities and the start time is more than or equal to the finish time of previously selected activity. We can sort the activities according to their ...
