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)+.…

矩阵乘法,顾名思义矩阵与矩阵相乘, 两矩阵可相乘的前提:第一个矩阵的行与第二个矩阵的列相等 相乘原则: a b * A B = a*A+b*C a*c+b*D c d C D = c*A+d*C c*A+d*C 上代码 struct matrix { ll a[maxn][maxn]; }; matrix matrix_mul(matrix x,matrix y) { matrix temp; ;i<=n;i++) ;j<=n;j++) { tem…
