Matrix Cells in Distance Order We are given a matrix with R rows and C columns has cells with integer coordinates (r, c), where 0 <= r < R and 0 <= c < C. Additionally, we are given a cell in that matrix with coordinates (r0, c0). Return the c…
这是小川的第384次更新,第412篇原创 01 看题和准备 今天介绍的是LeetCode算法题中Easy级别的第246题(顺位题号是1030).我们给出一个矩阵,其中R行和C列具有整数坐标(r,c)的单元格,其中0 <= r <R且0 <= c <C. 另外,我们在该矩阵中给出了一个坐标为(r0,c0)的单元格. 返回矩阵中所有单元格的坐标,按照它们从(r0,c0)到最小距离到最大距离的距离进行排序.这里,两个单元格(r1,c1)和(r2,c2)之间的距离是曼哈顿距离,|r1 -…

[算法]二分+矩阵快速幂 [题意]给定矩阵A和整数k,MOD,求A^0+A^1+A^2+...+A^k. [题解] 定义题目要求的答案为f(n),即: $$f_n=\sum_{i=0}^{n}A^i$$ 当n为偶数时,可以拆成两半,后一半由前一半集体乘A(n/2)得到,即: $$f_n=f_{\frac{n}{2}}(A^{\frac{n}{2}}+1)$$ 当n为奇数时,直接递推: $$f_n=f_{n-1}*A^n$$ 复杂度O(n^3 log k). 快速幂的单位矩阵是主对角线(左上到右下…
