EasyData EngineeringMatrixArraySorting
Description
Given a 2D array matrix, return all elements flattened into a single array in row-major order.
Examples
Input:
matrix = [[1,2],[3,4]]Output:
[1,2,3,4]Explanation:
Concatenating the rows in order yields [1,2,3,4].
Input:
matrix = [[5]]Output:
[5]Explanation:
Concatenating the rows in order yields [5].
Input:
matrix = [[1],[2],[3]]Output:
[1,2,3]Explanation:
Concatenating the rows in order yields [1,2,3].
Constraints
