What are jagged arrays and can you give me some examples?

Jagged arrays are arrays of arrays where the sub-arrays can have different lengths. For example, in a 2D jagged array, the first row might have 3 elements, and the second row might have 5.

Can you show me a code example of a jagged array in Python?

Sure! Here's a simple example in Python:

jagged_array = [[1, 2, 3], [4, 5], [6, 7, 8, 9]]

In this example, the first sub-array has 3 elements, the second has 2, and the third has 4.

What are the advantages of using jagged arrays?

Jagged arrays can save memory when the sub-arrays have varying sizes, as they only allocate space for the elements that are actually needed.

Are there any disadvantages to using jagged arrays?

Yes, one disadvantage is that accessing elements can be slightly more complex, and it may lead to less predictable performance compared to rectangular arrays.
