The merge sort for a linked list has to be of return type void and must take as its parameter the header to a linked list containing a head pointer and tail pointer (intialized to NULL if there are zero nodes). Otherwise, the supplementary functions merge and length can be of any ...

The basic idea is to first scan the list, find the middle point and break the list into two, sort two sub-lists recursively and merge them together. Obviously, time complexity would be O(nlogn). What is the space complexity? Since the function is called recursively and it uses stack spa...

Given a singly-linked list, where each node contains an integer value, sort it in ascending order. The merge sort algorithm should be used to solve this problem. Examples null, is sorted to null 1 -> null, is sorted to 1 -> null ...
