Help needed in DLDAG (December Long Challenge)

Please write a brief description of what you did and what problems are you facing. Is your code passing the sample input/output?

Edit— As far as I can see, whenever you are pushing a pair in the answer vector, the second argument is either -1 or 0.

So, your answer can never print out the type 2 queries correctly.
