FAQs
Why is it called asymptotic complexity?
Asymptotic complexity is so named because it focuses on how the performance of algorithms behaves as the input size approaches infinity. It examines the behavior of the upper bound, which allows us to understand how an algorithm evolves in the long run, which is similar to the concept
What is an example of asymptotic time complexity?
An example of asymptotic time complexity is O(n^2) complexity, often seen in algorithms with nested loops. This means that as the input size increases, the algorithm’s running time increases quadratically. Understanding such complexities
What are the 2 types of computational complexity?
The two main types of computational complexity are time complexity and space complexity. Time complexity measures how the execution time of an algorithm increases with the size of the input, while space complexity evaluates the amount of memory or space an algorithm requires to perform.
What is the difference between time complexity and computational complexity?
Time complexity focuses specifically on how the running time of an algorithm scales with the size of the input, providing information about efficiency. Computational complexity, on the other hand, encompasses both time complexity and space complexity, off
