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...
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)....

mergeSort(head: NodeObject | null, compare?: (val1, val2) => boolean): NodeObject | null Provide a noncircular linked list and it'll return a new sorted list. Defaults to ascending order. You can also provide a compare function that returns a boolean if the data to sort is nested ...
Sort a linked list inO(nlogn) time using constant space complexity. 一般merge sort在merge的过程中是需要额外空间的(对于一般的array),但是使用linked list就不需要了。 要注意slow和fast的写法。一遍通过,比较满意。 1 2 3 4 5 6 7 8 9 10 ...

2.1 Remove duplicates from linked list Write code to remove duplicates from an unsorted linked list. FOLLOW UP How would you solve this problem if a temporary buffer is not allowed? 方法1用set存已经访问的值。用了extra space。如果不用extra space需要O(n*n) 1 2 3 4 5 6 7 8 9 10 11 ...
Linked Lists - Move Node Write a MoveNode() function which takes the node from the front of the source list and moves it to the front of the destintation list. You should throw an error when the ...
Sort List 排序列表Description: Sort a linked list in O(n log n) time using constant space complexity.描述:使用常量空间复杂度在 O(n log n) 时间内对链表进行排序。Hint: Use merge sort or quick sort algorithm.提示:使用合并排序或快速排序算法。Solution: see here 解决办法:看这里 Remove Duplicates...
链表基础链表(Linked List)相比数组(Array),物理存储上非连续、不支持O(1)时间按索引存取;但链表也有其优点,灵活的内存管理、允许在链表任意位置上插入和删除节点。单向链表结构一般如下: //Definition for si…
