[1]. This was your code. I made a slight change with the header file. You code is giving wrong answers for the test cases given in the link.
This is my code which gives the right output.[here][2]
This is your corrected
3. You was using int. You were getting OVERFLOW. SO changed the data-type to unsigned long long int. Check this one now. Hope this will help you.
thanks for ur help bipin…the problem setter is definitely not worth being a problem setter at such a large scale event…he should have specified the max value of"n" more accurately…10000 is well within the limits to be accepted as int…thanks to you nevertheles
