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). InputThe input consists of multiple test cases. Each test case contains 3 integers A,…

主题链接: pid=1005">huangjing 题意: 就是给了一个公式,然后求出第n项是多少... 思路: 题目中n的范围实在是太大,所以肯定直接递推肯定会超时,所以想到的是暴力打表,找循环节,可是也不是那么easy发现啊,所以这时候分析一下,由于最后都会mod7,所以总共同拥有7X7总情况,即A 0,1,2,3,4,5,6,7.B也是如此,所以循环节为49,这么这个问题就攻克了. .. 题目: Number Sequence Time Limit: 2000/1000 MS (Ja…

f(n-1)和f(n-2)所有组合都49种子,这期可达49,但f(n-1)=f(n-2)=0如果是,列的总数目0.话题条件f(1)=f(2)=1.因此排除这样的情况.的最长期限48. #include<math.h> #include<stdio.h> #include<stdlib.h> #include<string.h> int main(void) { int a,b,n; int f[99]; while(scanf("%d%d%d&qu…

题目连接:10706 - Number Sequence 题目大意:有一个有0 ~ 9组成的序列,1   1 2    1 2 3   1 2 3 4   1 2 3 4 5 ....就是第一位为1. 第二为为1 ,第三为为2, 然后10 的部分注意下, 为1  和0 两个, 100 就是1 , 0和0 三位,以此类推, 要求给出tmp, 输出序列中的tmp位为什么数字. 解题思路:数据很大,肯定不能模拟,找规律. 这两个是为推出来的用来打表的公式: 1.sum[i] = sum[i - 1]…

HDU - 1711 A - Number Sequence   Given two sequences of numbers : a[1], a[2], ...... , a[N], and b[1], b[2], ...... , b[M] (1 <= M <= 10000, 1 <= N <= 1000000). Your task is to find a number K which make a[K] = b[1], a[K + 1] = b[2], ...... ,…
