A Simple Math Problem 一个矩阵快速幂水题,关键在于如何构造矩阵.做过一些很裸的矩阵快速幂,比如斐波那契的变形,这个题就类似那种构造.比赛的时候手残把矩阵相乘的一个j写成了i,调试了好久才发现.改过来1A. 贴个AC的代码: const int N=1e5+10; ll k,m,s[10]; struct mat { ll a[10][10]; }; mat mat_mul(mat A,mat B) { mat res; memset(res.a,0,sizeof(res.a…

题意:当x < 10时, f(x) = x: 当x >= 10 时,f(x) = a0 * f(x-1) + a1 * f(x-2) +  + a2 * f(x-3) + …… + a9 * f(x-10): ai(0<=i<=9) 只能是0或者1 ,给出a0 ~ a9,k和m,计算f(k)%m(k<2*10^9 , m < 10^5). 题目链接:http://acm.hdu.edu.cn/showproblem.php?pid=1757 ——>>构造矩阵…
