Today, I will focus mostly on Time Complexity from the Perl point of view.

1. O(1) - Constant Time
2. O(n) - Linear Time
3. O(log n) - Logarithmic Time
4. O(n ^ 2) - Quadratic Time
5. O(n log n) - Linearithmic Time
6. O(sqrt n) - Square Root Time
7. O(n ^ 3) - Cube Time
8. O(2 ^ n) - Exponential Time
9. O(n!) - Factorial Time
