Sort a linked list in O(n log n) time using constant space complexity.分析:题目要求时间复杂度为O(nlogn),所以不能用quickSort(最坏O(n^2)),可以使用mergeSort.对一个链表进行归并排序,首先注意归并排序的基本思想:找到链表的middle节点,然后递归对前半部分和后半部分分别进行归并排序,最后对两个以排好...
会产生新的头指针以及尾指针,要记录下来。在partition之后,要将小于pivot的的部分、pivot、以及大于pivot的部分又一次串起来成为一个singly linked list。 在partition时。我们用最后的节点作为pivot。当我们扫描链表时,假设节点值大于pivot,将节点移到尾部之后;假设节点小于。保持不变。 在递归排序时。我们先调用partitio...

147. Insertion Sort List Description Sort a linked list using insertion sort. Insertion Sort Definition Insertion sort is a simple sorting algorithm that works the way we sort playing cards in our hands. Insertion Sort Algorithm // Sort an arr[] of size n insertionSort(arr, n) Loop from i...
We will be implementing the simplest sorting algorithm, Bubble Sort, to sort the Linked List in increasing order. This sorting algorithm repeatedly swaps adjacent elements if placed in an unsorted order. This operation is performed repeatedly until all the elements are at their correct sorted positio...

An important consideration is the way you manage the list. Right now you are iterating over every element of the list to move it (or worse, copy it) to another list. Don't do that; Just cut and paste nodes. For example, code that splits the list should look something like this:...
