HDU 1005 Number Sequence(数论) 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 multipl…

HDU 4054 Number String 思路: 状态:dp[i][j]表示以j结尾i的排列 状态转移: 如果s[i - 1]是' I ',那么dp[i][j] = dp[i-1][j-1] + dp[i-1][j-2] + .. + dp[i-1][1] 如果s[i - 1]是‘D’,那么dp[i][j] = dp[i-1][j] + dp[i-1][j+1] + ... + dp[i-1][i] 用前缀和处理出sum[i][j]就不用dp[i][j]了 代码: #include<bits…

HDU 1711 Number Sequence (字符串匹配,KMP算法) Description Given two sequences of numbers : a1, a2, ...... , aN, and b1, b2, ...... , bM (1 <= M <= 10000, 1 <= N <= 1000000). Your task is to find a number K which make aK = b1, aK+1 = b2, ...... , aK+M…

HDU - 1005 Number Sequence 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…

Big Number 题意:算n!的位数. 题解:对于一个数来算位数我们一般都是用while去进行计算,但是n!这个数太大了,我们做不到先算出来在去用while算位数. while(a){ cnt++; a/=; } 将一个数对取10对数(取整),然后再加一就是这个数的位数,然后我们在算n!的时候每次对10取对数就好了. #include<iostream> #include<cmath> using namespace std; int main() { ios::sync_wi…
