HDU5015 233 Matrix(矩阵高速幂) 题目链接 题目大意: 给出n∗m矩阵,给出第一行a01, a02, a03 ...a0m (各自是233, 2333, 23333...), 再给定第一列a10, a10, a10, a10,...an0.矩阵中的每一个元素等于左边的加上上面的,求出anm. 解题思路: 先要依据矩阵元素的特征得出相乘的矩阵T, 然后就是求这个矩阵T的m次幂(这里就能够用矩阵高速幂),最后再和给定的第一列所形成的矩阵相乘,就能得到anm. 求矩阵T请參考 代码:…

题意:给出矩阵的第0行(233,2333,23333,...)和第0列a1,a2,...an(n<=10,m<=10^9),给出式子: A[i][j] = A[i-1][j] + A[i][j-1],要求A[n][m]. 解法:看到n<=10和m<=10^9 应该对矩阵有些想法,现在我们假设要求A[a][b],则A[a][b] = A[a][b-1] + A[a-1][b] = A[a][b-1] + A[a-1][b-1] + A[a-2][b] = ... 这样相当于右图:,红…
