I love slot machines, tell me where to play them, //array will start from index 1. Now we know that greedily choosing the activity with the least finish time will give us the optimal solution, so our first task would be to sort the activities with their finishing times. As we are only concerned with the number of activities and by replacing the activity, the number of activities will be the same. The Activity Selection problem is an approach to selecting non-conflicting tasks based on start and end time which can be solved in O (N logN) time using a simple greedy approach. Given the start time and end time of N activities, find the maximum number of activities that can be performed (Activity Selection problem) We can find the maximum number of activities using the greedy approach as indicated below 1. But, if we picked activity A2 first, the ending time is 20 and we see that A3 starting time is 20, which means that we can start this activiry as well. The activity selection problem can be used in scheduling multiple competing events in a room, such that each event has its own start and end time.

Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. Let's move to the next chapter and solve an interesting problem using the greedy algorithm. The next activity starts at time 3, which is after the finishing time of the previously selected activity 2. Here, we are going to learn about the solution of activity selection problem and its C++ implementation. A common difficulty in depression is the client's withdrawal from acitvities which were previously rewarding. // dp[i] stores the maximum non-conflicting activities till i'th activity, // # when `arr[j].finish` is less than equal to `arr[i].start`, // finding the vector having maximum size in dp, // printing activity with start and finish time, The maximum number of non-conflicting activities are {1, 3} {3, 4} {5, 9} {11, 12}, (arr.get(j).finish <= arr.get(i).start && dp.get(i).size() < dp.get(j).size()) {, // finding the vector having a maximum size in dp, // printing maximum non conflicting activity with start and finish time, The maximum number of non-conflicting activities are [(1, 3), (3, 4), (5, 9), (11, 12)], # dp[i] stores the maximum non-conflicting activities till i'th activity, # finding the list having maximum size in dp, # printing the list having maximum non-conflicting activities, Maximum non-conflicting activities are [[1, 3], [5, 9], [11, 12]], Your feedback is important to help us improve.
