Given a 2D array of integers (1D arrays to build a 2D array from), create a 1D array and fill it up with the sums of each column in the 2D array. Your first two lines of code must be:
int[][] arr = {row1, row2, row3};
int[] colSums = new int[arr[0].length];
array2D_colSums([1, 1], [-2, -2], [3, 3]) → [2, 2] array2D_colSums([-1, 2, 3], [4, -5, 6], [16, 2, -9]) → [19, -1, 0] array2D_colSums([1], [2], [6]) → [9] ...Save, Compile, Run (ctrl-enter) |
