What is the performance of nested loops in programming?
The performance of nested loops is generally O(n^2) for two loops, where n is the number of iterations.
Can you explain why it's O(n^2)?
Sure! Each iteration of the outer loop triggers the entire inner loop, leading to n * n iterations.
Are there ways to optimize nested loops?
Yes, you can optimize by reducing the number of iterations, using data structures, or applying algorithms like dynamic programming.
What are some common scenarios where nested loops are used?
Common scenarios include matrix operations, generating combinations, and comparing elements in two lists.
