What are some real-world examples of nested loops?

Nested loops are commonly used in programming for tasks like processing multi-dimensional arrays, generating combinations, or iterating through complex data structures.

Can you give me a specific example?

Sure! A common example is when you want to create a multiplication table. You can use a nested loop where the outer loop iterates through the numbers 1 to 10, and the inner loop multiplies each number by the current number of the outer loop.

That makes sense! Are there any performance concerns with nested loops?

Yes, nested loops can lead to performance issues, especially if both loops iterate over large datasets. The time complexity can increase significantly, so it's important to optimize them when possible.
