PYTHON Programming-Merge Sort for Doubly Linked List – Searching and Sorting – Merge sort for singly linked list is already discussed. The important change here is to modify the previous pointers also when merging two lists.
Binary Insertion Sort – Searching and Sorting – We can use binary search to reduce the number of comparisons in normal insertion sort. Binary Insertion Sort find use binary search to find the proper location to insert the selected item at each iteration.
QuickSort on Doubly Linked List – Searching and sorting -. The idea is simple, we first find out pointer to last node. Once we have pointer to last node, we can recursively sort the linked list using pointers to first and last nodes of linked list.
Merge Sort for Linked Lists – Searching and Sorting – Merge sort is often preferred for sorting a linked list. The slow random-access performance of a linked list makes some other algorithms (such as quicksort) perform poorly, and others (such as heapsort) completely impossible.
stability in sorting algorithms – Searching and Sorting – Some sorting algorithms are stable by nature like Insertion sort, Merge Sort, Bubble Sort, etc. And some sorting algorithms are not, like Heap Sort, Quick Sort.
Pigeonhole sort – Searching and sorting – Pigeonhole sorting is a sorting algorithm that is suitable for sorting lists of elements where the number of elements and the number of possible key values are approximately the same
Comb Sort – Searching and Sorting – Comb Sort is mainly an improvement over Bubble Sort. Bubble sort always compares adjacent values. So all inversions are removed one by one. Comb Sort improves on Bubble Sort by using gap of size more than 1.
ShellSort – Searching and Sorting – ShellSort is mainly a variation of Insertion Sort. In insertion sort, we move elements only one position ahead. When an element has to be moved far ahead, many movements are involved.
Bucket Sort – Searching and sorting – A simple way is to apply a comparison based sorting algorithm. The lower bound for Comparison based sorting algorithm (Merge Sort, Heap Sort, Quick-Sort .. etc) is Ω(n Log n), i.e., they cannot do better than nLogn.
