What are the performance issues with nested loops?

What are the performance issues with nested loops?

Nested loops can lead to significant performance degradation, especially with large datasets, due to their O(n^2) complexity.

Can you give me an example of when nested loops are particularly problematic?

Sure! For instance, if you have two lists of 1,000 items each, a nested loop would require 1,000,000 iterations.

How can I optimize my code to avoid these issues?

You can optimize by using algorithms that reduce the need for nested loops, like using hash maps for lookups.

Are there any specific programming languages that handle nested loops better?

Most languages handle nested loops similarly, but some, like Python, have built-in functions that can help reduce complexity.
