Difference between Comb Sort and Shell SortIn this tutorial, we will discuss comb sort, shell sort and the difference between them. Comb Sort is a more complex version of bubble Sort. Bubble Sort evaluates all nearby values, whereas comb sort eliminates all turtle values or small values near the end of the list. It is a contrast sorting algorithm that mostly improves on bubble sort. To sort the given array, bubble sort uses a comparison between nearby elements. As a result, the gap size between the components that are compared in bubble sort is 1. By employing a gap larger than one, comb sort outperforms bubble sort. The comb sort gap begins with the higher value and diminishes by a factor of 1.3. It indicates that when each phase is completed, the gap is divided by the shrink factor 1.3. The iteration process is repeated until the gap is equal to one. By running comb sort on 200,000 random lists, the shrink factor is found to be 1.3. Comb sort outperforms bubble sort, although its temporal complexity in the average and worst cases remains O(n^{2}). Shell sort is an extension of insertion sort that addresses insertion sort's disadvantages by evaluating elements separated by multiple locations. It is an expanded version of the insertion sort sorting algorithm. Insertion sort's average time complexity has been reduced thanks to shell sort. It is a contrast and inplace sorting algorithm, comparable to insertion sort. Shell sort works well for moderate data sets. Elements in insertion sort can only be moved forward by one position at a time. Many moves are necessary to transport an element to a distant point, which increases the algorithm's processing time. However, shell sort eliminates this disadvantage of insertion sort. It also enables for the moving and switching of distant elements. Implementation of the Comb SortLet's look at some Comb sort codes written in various coding languages. C Programming Language: Output: The output of the following code will be  Before sorting array elements are  49 11 24 44 29 27 2 After sorting array elements are  2 11 24 27 29 44 49 C++ Program: Output: The output of the following code will be  Before sorting array elements are  49 11 24 44 29 27 2 After sorting array elements are  2 11 24 27 29 44 49 Time Complexity:
The comb sort has a space complexity of O(1). Implementation of the Shell SortLet's look at some Shell sort codes written in various coding languages.
