What is the meaning of this lines:
For each case, output a single line consisting of the number of cards needed to
build a pyramid card of level N modulo 1,000,007.

useless question

kshitizmiglani: 2016-01-17 09:56:37

2 WA because question is not clear;
remember if f(n) is the real ans, modulo is not f(n%1000007), its f(n)%1000007

DP solution is acceptable but why not evaluate the formula.
