QuickSort on Singly Linked List – Searching and sorting – Quick Sort on Doubly Linked List is discussed here.In Singly linked list was given as an exercise. Following is C++ implementation for same.
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.
Merge Sort – searching and sorting algorithm – Like QuickSort, Merge Sort is a Divide and Conquer algorithm. It divides input array in two halves.
