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)....
Merge k sorted linked list就是merge 2 sorted linked list的变形题。 而且我们很自然的就想到了经典的Merge Sort,只不过那个是对数组进行sort。而不同的地方,仅仅是Merge两个list的操作不同。 这里来复习一下Merge Sort(对于数组操作),参考Wikipedia: 归并操作(merge),也叫归并算法,指的是将两个已经排序的序列...
Merge sort keeps on dividing the list into equal halves until it can no more be divided. By definition, if it is only one element in the list, it is sorted. Then, merge sort combines the smaller sorted lists keeping the new list sorted too. Step 1: if it is only one element in th...
Since the function is called recursively and it uses stack space, at any time during the execution there are at most O(logn) functions on the stack, therefore the space complexity is O(logn). The code is shown as follows: publicListNode sortList(ListNode head) {if(head==null|| head.nex...
刷题链接:https://leetcode-cn.com/problems/merge-sorted-array/ 在这里提供两套解题思路: 直接将nums1后续的值填满,调用Arrays.sort...不断++,则可不断获得n-1,n-2,n-3的值。即可成功解题。 public voidmerge(int[]nums1, int m, int[]nums2, int n) { for(int ...
Using pointers on lists and mixing them (sort) can sometimes lead your code to suffer from high complexity will eventually can lead to bugs and errors. There tools who help to deal with those as checkmarx but it is recommended to make sure you code correctly and detect mistakes as you cod...
