题目链接 题意: 思路: 直接拿别人的图,自己写太麻烦了~ 然后就可以用矩阵快速幂套模板求递推式啦~ 另外: 这题想不到或者不会矩阵快速幂,根本没法做,还是2013年长沙邀请赛水题,也是2008年Google Codejam Round 1A的C题. #include <bits/stdc++.h> typedef long long ll; const int N = 5; int a, b, n, mod; /* *矩阵快速幂处理线性递推关系f(n)=a1f(n-1)+a2f(n-2)+.…
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%…
