Returnanm x n2D array constructed according to the above procedure, or an empty 2D array if it is impossible. Example 1: Input:original = [1,2,3,4], m = 2, n = 2Output:[[1,2],[3,4]]Explanation:The constructed 2D array should contain 2 rows and 2 columns. The first group of...
Given an m * n matrix M initialized with all 0's and several update operations. Operations are represented by a 2D array, and each operation is represented by an array with two positive integers a and b, which means M[i][j] should be added by one for all 0 <= i < a and 0 <=...
