Merge sort is often the best choice for sorting a linked list: in this situation it is relatively easy to implement a merge sort in such a way that it requires only Θ(1) extra space, and the slow random-access performance of a linked list makes some other algorithms (such as quicksort) perform poorly, and others (such as heapsort) completely ...
Merge sort's requirement for Ω(n) extra space (roughly half the size of the input) is usually prohibitive except in the situations where merge sort has a clear advantage: When a stable sort is required; When taking advantage of (partially) pre-sorted input; Sorting linked lists (in which case merge sort requires minimal extra space)
Singly linked lists contain nodes which have a 'value' field as well as 'next' field, which points to the next node in line of nodes. Operations that can be performed on singly linked lists include insertion, deletion and traversal. A singly linked list whose nodes contain two fields: an integer value (data) and a link to the next node
Merge sort works very well on linked lists, requiring only a small, constant amount of auxiliary storage. Although quicksort can be implemented as a stable sort using linked lists, there is no reason to; it will often suffer from poor pivot choices without random access, and is essentially always inferior to merge sort.

Thus it can get the best features of a sorted array (for searching) while maintaining a linked list-like structure that allows insertion, which is not possible with a static array. Fast search is made possible by maintaining a linked hierarchy of subsequences, with each successive subsequence skipping over fewer elements than the previous one ...
Strand Sort Animation. Strand sort is a recursive sorting algorithm that sorts items of a list into increasing order. It has O(n 2) worst-case time complexity, which occurs when the input list is reverse sorted. [1] It has a best-case time complexity of O(n), which occurs when the input is already sorted. [citation needed]
Selection sort animation. Red is current min. Yellow is sorted list. Blue is current item. (Nothing appears changed on these last two lines because the last two numbers were already in order.) Selection sort can also be used on list structures that make add and remove efficient, such as a linked list.
