题目链接 http://acm.hdu.edu.cn/showproblem.php?pid=4990 题意 初始的ans = 0 给出 n, m for i in 1 -> n 如果 i 为奇数 ans = (ans * 2 + 1) % m 反之 ans = ans * 2 % m 思路 如果我们只计算 偶数项 那么递推公式就是 ans[n] = 4 * ans[n - 2] + 2 如果 n 是偶数 那么刚好 就按这个公式推 第 n / 2 项 如果 n 是奇数 那么就是 第 [ n /…
题目大意:就是给出a,b,n,m:让你求s(n); 解题思路:因为n很可能很大,所以一步一步的乘肯定会超时,我建议看代码之前,先看一下快速幂和矩阵快速幂,这样看起来就比较容易,这里我直接贴别人的推导,应该很容易懂. 看到这里你应该明白了大概吧!好吧现在继续看我的代码吧!! AC代码: #include<stdio.h> long long c[2][2],d[2]; int main() { long long a,b,n,m,x,y,p,q; while(scanf("%I64d%…
思路:一开始不会n^4的推导,原来是要找n和n-1的关系,这道题的MOD是long long 的,矩阵具体如下所示 最近自己总是很坑啊,代码都瞎吉坝写,一个long long的输入写成%d一直判我TLE,一度怀疑矩阵快速幂地复杂度orz 代码: #include<set> #include<cstring> #include<cstdio> #include<algorithm> #define ll long long const int maxn = 7…
