快速幂算法可以说是ACM一类竞赛中必不可少,并且也是非常基础的一类算法,鉴于我一直学的比较零散,所以今天用这个帖子总结一下 快速乘法通常有两类应用:一.整数的运算,计算(a*b) mod c 二.矩阵快速乘法 一.整数运算:(快速乘法.快速幂) 先说明一下基本的数学常识: (a*b) mod c == ( (a mod c) * (b mod c) ) mod c //这最后一个mod c 是为了保证结果不超过c 对于2进制,2n可用1后接n个0来表示.对于8进制,可用公式 i+3*j ==…
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…
