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. WebOct 5, 2024 · An algorithm's time complexity specifies how long it will take to execute an algorithm as a function of its input size. Similarly, an algorithm's space complexity specifies the total amount of space or … WebOne implementation can be described as arranging the data sequence in a two-dimensional array and then sorting the columns of the array using insertion sort. The worst-case time complexity of Shellsort is an open problem and depends on the gap sequence used, with known complexities ranging from O(n 2) to O(n 4/3) and Θ(n log 2 n). can heart failure cause night sweats
