instructions for the output could really be clearer, taught me that we should all remember to explain ourselves better ;-) for the benefit for the people doing this question, the output requests for (number of cards needed to make n levels) mod 1000007, not number of cards needed to make (n mod 1000007) levels. |

Take long long int in place of int. I got one WA because of that. Easy problem. Try this after solving above problem: http://www.spoj.com/problems/TRICOUNT/ |
