【HDOJ】3221 Brute-force Algorithm 归来吧很好推导。T(n) = a^f(n-1)*b^f(n)%p。 主要难点在于求mod和fibo。引用如下公式 A^B%C = A^(B%phi(C) + phi(C))%C, 满足B>=phi(C)。 1/**/2#include <iostream>3#include <string>4#include 5#include <queue>6#include <set>7#include <...

但是如果n很大,(f[45] 就要超过int了) 这样就得用欧拉定理了 ,是用a和m不互素的那种,但是不可能存得下那么多数,所以我们基于线性递推数列,模上一个数后必然出现周期这样的结论,猜想会在不超过数组范围内出现周期(事实上为什么一定会在1000000内出现还是没有证明)。
