这道题普通做法会发生溢出且会超时,应当用快速幂来求解. 快速幂讲解 #include <cstdio> #include <cmath> using namespace std; int main(){ int Z; scanf("%d",&Z); while(Z--){ int M, H; unsigned ; scanf("%d%d",&M,&H); ; i < H; i++){ long long a,b;…
题目链接 请猛戳~ Description Given a n × n matrix A and a positive integer k, find the sum S = A + A2 + A3 + … + Ak. Input The input contains exactly one test case. The first line of input contains three positive integers n (n ≤ 30), k (k ≤ 109) and m (m <…
地址 http://poj.org/problem?id=3233 大意是n维数组 最多k次方 结果模m的相加和是多少 Given a n × n matrix A and a positive integer k, find the sum S = A + A2 + A3 + … + Ak. Sample Input 2 2 4 0 1 1 1 Sample Output 1 2 2 3 题解 矩阵逐步的相乘然后相加是不可以 但是矩阵也有类似快速幂的做法 /*A + A^2 =A(I+A)…
