i have doubts in miscof answer , your question says that given graph is a DAG ,but in miscof's reply he is considering directed graph which contain say n strongly connected component , so if we consider dat there are n strongly connected component in your graph then that graph is not a DAG(this

oh ok .. but then i think this ques should have a adv version for cyclic too bcoz anyhow u have to make it at last a cyclic to make it fully connected then why not the input should be like that. Thanks On Tue, Oct 9, 2012 at 10:13 PM, Saurabh Kumar srbh.ku...@gmail.com wrote: We are attempting

ok the algo will go like this : count no of nodes having only indegree 0 , only outdegree 0 and both 0. say in_count,out_count and both_count are the corresponding counts. now decrease the counts accordingly if u found a matching like u can decrease in_count by both_count if both_countin_count ie.
