Sorting algorithm, in computer science, a procedure for ordering elements in a list by repeating a sequence of steps. Sorting algorithms allow a list of items to be sorted so that the list is more usable than it was, usually by placing the items in numer

Measuring Efficiency With Big O Notation The specific time an algorithm takes to run isn’t enough information to get the full picture of its time complexity. To solve this problem, you can use Big O (pronounced “big oh”) notation. Big O is often used to compare different implementations...

Its worst-case time complexity is $O(n^2)$ when the pivot is chosen poorly, making it less efficient than other algorithms like merge sort or heapsort in certain situations. Technical Note: we don’t want to choose a pivot that’s too small or too big, or the algorithm will run in...
Big O: O(N log N) Merge sort is a perfect example of a Divide and Conquer algorithm. It simply uses the 2 main steps of such an algorithm: Dividethe unsorted list until you have N sublists. Each sublist has 1 element that is unsorted and N is the number of elements in the origina...
