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...
intN, n, temp; element_t* node = list->head; N = list_length( list );// Don't sort an unsortable listif(N < 2)return;// just swap the two elements if necessaryif(N == 2) {if(list->head->val > list->tail->val) { temp = list->head->val; list->head->val = list...
I implemented merge sort with my own linked list for a school project. I was not allowed to use anything but the methods you see in the list. It seems to work properly, however, when running the provided testbed, I am told that the implementation is likely O(n2)O(n2)....
