Leetcode 566. Reshape the Matrix 矩阵变形(数组,模拟,矩阵操作) 题目描述 在MATLAB中,reshape是一个非常有用的函数,它可以将矩阵变为另一种形状且保持数据不变. 已知一个由二维数组表示的矩阵,和两个正整数r(行),c(列),将这个二维数组变换为r*c的矩阵. 如果不能由原矩阵转换为r*c的矩阵就输出原矩阵,否则输出转换后的矩阵. 测试样例 Input: nums = [[1,2], [3,4]] r = 1, c = 4 Output: [[1,2,…

在MATLAB中,有一个非常有用的函数 reshape,它可以将一个矩阵重塑为另一个大小不同的新矩阵,但保留其原始数据. 给出一个由二维数组表示的矩阵,以及两个正整数r和c,分别表示想要的重构的矩阵的行数和列数. 重构后的矩阵需要将原始矩阵的所有元素以相同的行遍历顺序填充. 如果具有给定参数的reshape操作是可行且合理的,则输出新的重塑矩阵:否则,输出原始矩阵. 示例 1: 输入: nums = [[1,2], [3,4]] r = 1, c = 4 输出: [[1,2,3,4]] 解释:…

1. 题目大意 根据给定矩阵,重塑一个矩阵,r是所求矩阵的行数,c是所求矩阵的列数.如果给定矩阵和所求矩阵的数据个数不一样,那么返回原矩阵.否则,重塑矩阵.其中两个矩阵中的数据顺序不变(先行后列). 2. 思路 由于矩阵中数据顺序不变,因此我们考虑按顺序做.原矩阵中的第i行第j列(从0开始)的数据可以记为第k个数,其中k=i*(原矩阵中的列数)+j.对应的是新产生的矩阵中的第k/c行,k%c列的元素.一一赋值.这题的关键是要小心数组的边界,正确找到对应的位置. 3. 代码 class Solut…
