What are some real-world examples of jagged arrays?

Can you give me some real-world examples of jagged arrays?

Sure! Jagged arrays are arrays of arrays where each sub-array can have a different length. For example, in a school database, you might have a jagged array to store students' grades for different subjects, where each student has a different number of grades.

That makes sense! Can you give me another example?

Absolutely! Another example is in image processing, where you might use a jagged array to represent pixel data for images of varying dimensions. Each row in the jagged array could represent a different image with a different width.

Interesting! Are there any performance considerations with jagged arrays?

Yes, there are! Jagged arrays can be more memory efficient for certain applications, but accessing elements can be slower compared to rectangular arrays due to the additional indirection.

Thanks for the info! How do I implement a jagged array in Python?

In Python, you can create a jagged array using lists. For example: jagged_array = [[1, 2, 3], [4, 5], [6]] creates a jagged array with three sub-arrays of different lengths.
