Activity Selection Question Explain

#1

Please explain the question once, did’nt get how the output was 2 .
Is this like the 0th activity started at 10 and ended at 20 and the 2nd activity started at 20 and ended at 30 so maximum time was consumed here.
OR is it according to difference in maximum time spend, don’t know, clarify it once please.

Hello @Sakshi2004
in this you should take the input in the pair format and then sort the pairs according to their ending time and then you can check if the ending time of the current meeting is greater then the starting time of the next meeting then you need to increment the counter.
Here for your reference i am attaching the code:


if you have any doubt you can ask here

In this the trick is to keep the track of the previous ongoing meeting and to check the time with the ending of that.
