What are some advanced loop techniques in programming?

Advanced loop techniques include nested loops, loop unrolling, and using iterators for better performance.

Can you explain nested loops with an example?

Sure! A nested loop is a loop inside another loop. For example, in Python:

for i in range(3):
    for j in range(2):
        print(i, j)

This will print pairs of i and j.

What is loop unrolling and why is it used?

Loop unrolling is an optimization technique that reduces the overhead of loop control. By executing multiple iterations in a single loop iteration, it can improve performance.

Are there any drawbacks to using advanced loop techniques?

Yes, advanced techniques can lead to increased complexity and may affect readability. It's important to balance performance with maintainability.
