hi @Ishitagambhir can pls take a look at my doubt
here : 'Course Schedule' Problem .Can you help me optimize my code

#5

@amitqy @chhavibansal has already responded to your doubt there. You have to apply topological sort here.

#6

The approach I am using is very similar to topological sort, we do a topo sort only if the graph does not have any cycle. So I am checking if the graph has cycle or not. Most voted answer there is also using cycle detection
