2. Insertion Sort, 将arr分为左边(sorted array)和右边(unsorted array),然后依次将unsorted array的元素insert到sorted array里面。 T: O(n ^ 2), S: O(1) 同样的思路[LeetCode] 147. Insertion Sort List_Middle tag: Linked List 3. Merge Sort, 将array 分成两半,然后在merge两个sorted array, 每次...
下面是quickSort,因为quickSort算法的最坏情况是O(n*n), 所以如果做LeetCode上的Sort List这道题目,会遇上最坏情况超时的,不过这是个很好的算法,故此贴出来。 参考网站: http://www.geeksforgeeks.org/quicksort-on-singly-linked-list/ 也看了有些博客或什么网站也写有quickSort排序链表的文章,注意看清楚了...
