题目: Sort a linked list using insertion sort. 解题思路: 按题目要求,直接进行插入排序 实现代码: #include <iostream> using namespace std; /* Sort a linked list using insertion sort. */ struct ListNode { int val; ListNode *next; ListNode(int x):val(x), next(NULL){} }; void a…
Sort a linked list using insertion sort. A graphical example of insertion sort. The partial sorted list (black) initially contains only the first element in the list.With each iteration one element (red) is removed from the input data and inserted in…
Sort List Sort a linked list in O(n log n) time using constant space complexity. Have you been asked this question in an interview? Yes 说明:归并排序: 时间 O(nlogn),空间 O(1). 每次将链表一分为二, 然后再合并.快排(用两个指针) /** * D…
Sort a linked list using insertion sort. Subscribe to see which companies asked this question 解答 对于链表的插入排序,用tmp_tail遍历链表,每次的待插入数是tmp_tail->next的元素,待插入数必须从头开始比较,当然从头开始比较时要注意处理待排序数小于或等于链表首元素的情况,因为插入在链表的首元素之前与一般情况的插入不同,而如果待插入数插入在它之前的数列中,则用于遍历链表的指针tmp_ta…
