HDU 5667 构造矩阵快速幂 题目描述 解析 我们根据递推公式 设 则可得到Q的指数关系式 求Q构造矩阵 同时有公式 其中φ为欧拉函数,且当p为质数时有 代码 #include <cstdio> using namespace std; long long pow_mod(long long a, long long p, long long mod) { if (p == 0) return 1; long long ans = pow_mod(a, p / 2, mod); ans =…

Yet Another Number Sequence Description Everyone knows what the Fibonacci sequence is. This sequence can be defined by the recurrence relation: F1 = 1, F2 = 2, Fi = Fi - 1 + Fi - 2 (i > 2). We'll define a new number sequence Ai(k) by the formula: Ai(…

There is a special number sequence which has n+1 integers. For each number in sequence, we have two rules: ● a i ∈ 0,n0,n ● a i ≠ a j( i ≠ j ) For sequence a and sequence b, the integrating degree t is defined as follows("�" denotes exclusive or…
