Alice is given a list of integers by Bob and is asked to generate a new list where each element in the new list is the sum of some other integers in the original list. The task is slightly more involved, as Bob also asks Alice to repeat this several…
UVA 11551 - Experienced Endeavour 题目链接 题意:给定一列数,每一个数相应一个变换.变换为原先数列一些位置相加起来的和,问r次变换后的序列是多少 思路:矩阵高速幂,要加的位置值为1.其余位置为0构造出矩阵,进行高速幂就可以 代码: #include <cstdio> #include <cstring> const int N = 55; int t, n, r, a[N]; struct mat { int v[N][N]; mat() {mem…
题目链接 题意: 思路: 直接拿别人的图,自己写太麻烦了~ 然后就可以用矩阵快速幂套模板求递推式啦~ 另外: 这题想不到或者不会矩阵快速幂,根本没法做,还是2013年长沙邀请赛水题,也是2008年Google Codejam Round 1A的C题. #include <bits/stdc++.h> typedef long long ll; const int N = 5; int a, b, n, mod; /* *矩阵快速幂处理线性递推关系f(n)=a1f(n-1)+a2f(n-2)+.…

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…
