原题链接:http://acm.hdu.edu.cn/showproblem.php?pid=1005 主要内容: A number sequence is defined as follows: f(1) = 1, f(2) = 1, f(n) = (A * f(n - 1) + B * f(n - 2)) mod 7. Given A, B, and n, you are to calculate the value of f(n). 看到这样的公式很容易想到递归调用求解,但是在本题中n的取…

Problem Description A number sequence is defined as follows: f(1) = 1, f(2) = 1, f(n) = (A * f(n - 1) + B * f(n - 2)) mod 7. Given A, B, and n, you are to calculate the value of f(n). Input The input consists of multiple test cases. Each test case co…

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