When should I use deep copy in programming?

When should I use deep copy in programming?

You should use deep copy when you need to create a completely independent copy of an object, including all nested objects.

Can you give me an example of when deep copy is necessary?

Sure! If you have a list of objects and you want to modify one of them without affecting the others, a deep copy is essential.

What happens if I use shallow copy instead?

With shallow copy, changes to nested objects will affect the original object, as they share references.

Are there performance implications of using deep copy?

Yes, deep copy can be slower and consume more memory than shallow copy, especially with large or complex objects.
