Prerequisite: Merge Sort for Linked Lists
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.
Input : 5 -> 4 -> 3 -> 2 -> 1
Output :1 -> 2 -> 3 -> 4 -> 5
Input : 10 -> 20 -> 3 -> 2 -> 1
Output : 1 -> 2 -> 3 -> 10 -> 20
10 -> 20 -> 3 -> 2 -> 1 After sorting : 1 -> 2 -> 3 -> 10 -> 20
