What are the differences between 1D and 2D arrays?

What are the differences between 1D and 2D arrays?

1D arrays are linear structures that store elements in a single row, while 2D arrays are grid-like structures with rows and columns.

Can you give me an example of each?

Sure! A 1D array could be: [1, 2, 3, 4], and a 2D array could be: [[1, 2], [3, 4]].

How do I access elements in these arrays?

In a 1D array, you access elements using a single index, like array[0]. In a 2D array, you use two indices, like array[0][1].

Are there any performance differences when using them?

Yes, 1D arrays are generally faster for linear data access, while 2D arrays can be more complex but useful for representing matrices.
