What are some alternatives to nested loops in programming?

There are several alternatives to nested loops, such as using recursion, list comprehensions, or higher-order functions like map and filter.

Can you explain how recursion can replace nested loops?

Sure! Recursion allows a function to call itself, which can help break down problems into smaller subproblems, eliminating the need for nested loops.

What about using list comprehensions? How do they work?

List comprehensions provide a concise way to create lists. They can replace nested loops by combining loops and conditional logic in a single line.

Are there any performance considerations when using these alternatives?

Yes, performance can vary. Recursion may lead to stack overflow for deep calls, while list comprehensions can be more memory efficient but may not always be faster than loops.
