What is the difference between Big O and Big Theta notation?
Big O notation describes an upper bound on the time complexity, while Big Theta provides both upper and lower bounds.
Can you give me an example of each?
Sure! For example, if an algorithm runs in O(n^2), it means it won't take longer than that. If it runs in Θ(n^2), it means it takes that time in the worst and best cases.
Why is it important to understand these notations?
Understanding these notations helps in analyzing the efficiency of algorithms, which is crucial for optimizing performance.
Are there other notations I should know about?
Yes, besides Big O and Big Theta, there's also Big Omega, which describes a lower bound on time complexity.
