How do nested loops and conditionals work in programming?

Nested loops are loops within loops, allowing you to iterate over multi-dimensional data. Conditionals let you execute code based on certain conditions.

Can you give me an example of nested loops with conditionals?

Sure! Here's a simple example in Python:

for i in range(3):  # Outer loop
    for j in range(2):  # Inner loop
        if i == j:
            print(f'Equal: {i} and {j}')
        else:
            print(f'Not equal: {i} and {j}')

What are some common use cases for nested loops?

Common use cases include processing multi-dimensional arrays, generating combinations, and working with matrices.

Are there any performance concerns with using nested loops?

Yes, nested loops can lead to increased time complexity, especially with large datasets. It's important to optimize them when possible.
