Course schedule extended

Revision en1, by __SAK__, 2022-10-01 11:02:05

You might have seen the problem Course Schedule on Leetcode [] Here the ans just comes down to finding if there exists a cycle in the graph or not. I wanted to find the how many total courses can I take if not all the courses. One approach I thought was a multisource BFS with maintaining the indegree for each node and updating it but it would be quite slow. Can anyone suggest any faster method?
