传送门 矩阵快速幂板题,写一道来练练手. 这一次在poj做题总算没忘了改万能库. 代码: #include<iostream> #include<cstdio> #define mod 10000 #define A a[0][0] #define B a[0][1] #define C a[1][0] #define D a[1][1] using namespace std; int n; struct Matrix{int a[2][2];Matrix(){A=0,B=C=D…
题目分析: 对于给出的n,求出斐波那契数列第n项的最后4为数,当n很大的时候,普通的递推会超时,这里介绍用矩阵快速幂解决当递推次数很大时的结果,这里矩阵已经给出,直接计算即可 #include<iostream> #include<stdio.h> using namespace std; ; struct mat{ ][]; }; mat operator * (mat a, mat b){ //重载乘号,同时将数据mod10000 mat ret; ; i < ; i++…
