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++…
Description Let's consider one interesting word game. In this game you should transform one word into another through special operations. Let's say we have word w, let's split this word into two non-empty parts x and y so, that w = xy. A split operat…
