Topological sorting
My ques. is not the no. of topological sort as i have computed it myself. My problem is can someone please telll me a efficient approach as tree method is taking a lot of time here, like by use of combinatorics, can we find it easily, i.e in less time. and if possible, pls provide general approach apart from tree method.
