A typical example of O(N log N) would be sorting an input array with a good algorithm (e.g. mergesort). A typical example if O(log N) would be looking up a value in a sorted input array by bisection. gravity finance

"Web16 de ago. de 2024 · Logarithmic time complexity log(n): Represented in Big O notation as O(log n), when an algorithm has O(log n) running time, it means that as the input size grows, the number of operations grows very slowly. Example: binary search. So I think now it’s clear for you that a log(n) complexity is extremely better than a linear complexity O(n). " - O n notation example
