Problem DescriptionM斐波那契数列F[n]是一种整数数列,它的定义如下: F[0] = aF[1] = bF[n] = F[n-1] * F[n-2] ( n > 1 ) 现在给出a, b, n,你能求出F[n]的值吗? Input输入包含多组测试数据:每组数据占一行,包含3个整数a, b, n( 0 <= a, b, n <= 10^9 ) Output对每组测试数据请输出一个整数F[n],由于F[n]可能很大,你只需输出F[n]对1000000007取模后的值即可,…

题意:给定一个矩阵的第0列的第1到n个数,第一行第1个数开始每个数分别为233, 2333........,求第n行的第m个数. 分析: 其实也没那么难,自己想了半天还没往对的方向想,m最大1e9,应该立即想到要用到快速幂,关键在于递推矩阵. 递推矩阵的作用是依次算出每一列,第1列第一个数233是前一列的23*10+3,将前一列增加一个元素[3, 23, a1, a2,....an],然后第一列第一个数为3,对应向量[1, 0, 0, 0.....0],233对应向量[1, 10, 0, ...…

http://acm.hdu.edu.cn/showproblem.php?pid=5015 由于是个二维的递推式,当时没有想到能够这样构造矩阵.从列上看,当前这一列都是由前一列递推得到.依据这一点来构造矩阵.令b[i]代表第i列,是一个(n+2)*1的矩阵,即b[1] = [1,233......],之所以在加了两行,是要从前一个矩阵b[i-1]得到b[i]中的第二个数2333...,再构造一个转换矩阵a,它是一个(n+2)*(n+2)的矩阵,那么a^(m-1) * b就是第m列. /* a矩…
