@raman3217, your code is giving wrong no of scc's. For e.g
1 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.

regarding question https://www.codechef.com/BLUP2019/problems/GRAPHCOL

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 https://www.codechef.com/viewsolution/22917799
