algorithm - Which is better: O(n log n) or O(n^2) - Stack Overflow

stackoverflow.com

Just ask wolframalpha if you have doubts. In this case, it says. N log(n) lim - = 0. N^2. Or you can also calculate the limit yourself: N log(n) log(n) (Hôpital) 1/n 1 lim - = lim - = lim - = lim --- = 0. N^2 n 1 n. That means n^2 grows faster, so n log(n) is smaller (better), when n is high enough.

big o - Which algorithm is faster O(N) or O(2N)? - Stack Overflow

stackoverflow.com

The definition of big O is: O(f(n)) = { g | there exist N and c > 0 such that g(n) < c * f(n) for all n > N }. In English, O(f(n)) is the set of all functions that have an eventual growth rate less than or equal to that of f. So O(n) = O(2n).
