WebApr 10, 2015 · Sorted by: 23. Let's go through the cases for Big O for Bubble Sort. Case 1) O (n) (Best case) This time complexity can occur if the array is already sorted, and that means that no swap occurred and only 1 iteration of n elements. Case 2) O (n^2) (Worst case) The worst case is if the array is already sorted but in descending order. WebTime and space complexity.
