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

Your graph is not acyclic. :)

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

This DAG contains only one cut vertex(B) but we need to add two edges to
make it strongly connected.

count the no. of nodes having 0 in-degree.

yeah you are correct bharat .. so i think it should be no. of nodes having
0 (in-degree + out-degree). what say ?

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.
@atul : if there is no cut vertex, that doesn't mean that graph is strongly
connected ...
