WebJun 10, 2024 · Space and time complexity acts as a measurement scale for algorithms. We compare the algorithms on the basis of their space (amount of memory) and time complexity (number of operations). The total amount of the computer's memory used by an algorithm when it is executed is the space complexity of that algorithm. 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.
