对左边子数组排序时,子数组右边界是middle-1,如果链表也按这种两边都是闭区间的话,找到分割后枢纽元middle,找到middle-1还得再次遍历数组,因此链表的partition采用前闭后开的区间(这样排序主函数也需要前闭后开区间),这样就可以避免上述问题
ListNode* head2 = walker->next; walker->next =NULL;//非常重要,将链表断开,一分为二head1 =sortList(head1); head2 =sortList(head2);returnmergeTwoLists(head1, head2); }ListNode *mergeTwoLists(ListNode *l1, ListNode *l2){if(l1 ==NULL)returnl2;elseif(l2 ==NULL)returnl1; ListNode *R...
Sort a linked list inO(nlogn) time using constant space complexity. 题目要求使用O(nlogn)时间复杂度,可以考虑使用归并排序,在merge two sorted lists中,已经知道了将两个有序链表进行合并。这里只要在这基础上修改。 排序算法入门之归并排序(java实现)说了数组的归并排序, 使用归并排序。每次要找到中间元素进行...

148. Sort List Sort a linked list inO(nlogn) time using constant space complexity. Example 1: Input:4->2->1->3Output:1->2->3->4 Example 2: Input:-1->5->3->4->0Output:-1->0->3->4->5 思路: 题目意思很明确,给一个链表排序,排序的方式有很多,这里写一下归并排序。
Sort a linked list in O(n log n) time using constant space complexity. Example 1: Input: 4->2->1->3 Output: 1->2->3->4 Example 2: Input: -1->5->3->4->0 Output: -1->0->3->4->5 思路: 常见排序方法有很多,插入排序,选择排序,堆排序,快速排序,冒泡排序,归并...
