regarding question

my solution approach is to find the no of sccs and check if k<(no of sccs) then answer is -1

else ans=ncr(k,no of sccs )*factorial[no of sccs]

can anybody check what is wrong in my approach


@raman3217, your code is giving wrong no of scc’s. For e.g

3 6 7
1 2
2 3
3 1
2 4
4 5
5 6
6 4

no of scc are 2, whereas your code gives 6.


On Contest page, duration is written 3 hours but end time - start time given here is 2 hours!


@shivam_g1470 My apologies, it is fixed now. Thanks for reporting :slight_smile:
