An algorithm’s Big-O notation is determined by how it responds to different sizes of a given dataset. For instance how it performs when we pass to it 1 element vs 10,000 elements. O stands for Order Of, so O (N) is read “Order of N” — it is an approximation of the duration of the algorithm given N input elements.This is a repository containing the list of company wise questions available on leetcode premium.

Big O ignores constants, but sometimes the constants matter. If we have a script that takes 5 hours to run, an optimization that divides the runtime by 5 might not affect big O, but it still saves you 4 hours of waiting. Beware of premature optimization. Sometimes optimizing time or space negatively impacts readability or coding time.
