What are some real-world examples of nested loops?

Can you give me some real-world examples of nested loops?

Sure! Nested loops are often used in programming for tasks like processing multi-dimensional arrays or generating combinations. For example, if you want to create a multiplication table, you would use a nested loop to iterate through each number and multiply it by every other number.

That makes sense! Can you give me another example?

Absolutely! Another example is when you need to compare items in a list against each other, like finding duplicates. You would use a nested loop to check each item against all others.

Are there any performance concerns with nested loops?

Yes, nested loops can lead to performance issues, especially with large datasets, as their time complexity can grow significantly. It's important to consider alternatives when possible.
