Which of the following arrays is a two dimensional (2-D) array?89[1,2,3,4][1,2,3],[3,4,5],[1,3,4][[2 3 5][ 4 5 6][4 5 6]]
Question
Which of the following arrays is a two dimensional (2-D) array?89[1,2,3,4][1,2,3],[3,4,5],[1,3,4][[2 3 5][ 4 5 6][4 5 6]]
Solution
The two-dimensional array from the options you provided is [[2 3 5][ 4 5 6][4 5 6]].
Here's why:
A two-dimensional array is essentially an array of arrays. It can be visualized as a grid with x and y coordinates.
In the option [[2 3 5][ 4 5 6][4 5 6]], you can see that it is an array containing three other arrays. Each of these inner arrays ([2 3 5], [4 5 6], and [4 5 6]) can be seen as a row in the grid.
So, this is a 2-D array with 3 rows and 3 columns.
The other options are not 2-D arrays.
89 is a single integer, not an array.
[1,2,3,4] is a one-dimensional array with 4 elements.
[1,2,3],[3,4,5],[1,3,4] are three separate one-dimensional arrays, not a single 2-D array.
