一把神奇的锁锁住了真理之刃，所上刻这一系列奇怪的数字。CydorniaKnight告诉Dastan，这些数字有一个规律，都是组合数：

C(M,N)=M!/(N!(M-N)!)

而开锁的钥匙就是满足条件的最小M

为了拔出真理之刃，Dastan需要计算出所有M

-A magical lock to the edge of the truth, engraved on this series of odd numbers. CydorniaKnight tell Dastan, these figures have a rule, are the number of combinations: C (M, N) = M/(N! (MN)) and unlock the key is to satisfy the conditions of minimum M in order to pull out the edge of the truth, the Dastan need to calculate all M
