Sort a linked list using insertion sort. 链表的插入排序. 需要创建一个虚拟节点.注意点就是不要节点之间断了. class Solution { public: ListNode* insertionSortList(ListNode* head) { if(head==NULL||head->next==NULL) return head; ListNode* newhead = ); newhead->next=head; ListNode* q=h…

Insertion Sort List 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…

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…

题目如下: Given two arrays arr1 and arr2, the elements of arr2 are distinct, and all elements in arr2 are also in arr1. Sort the elements of arr1 such that the relative ordering of items in arr1 are the same as in arr2.  Elements that don't appear in arr…

原题 Given an unsorted array nums, reorder it in-place such that nums[0] <= nums[1] >= nums[2] <= nums[3].... For example, given nums = [3, 5, 2, 1, 6, 4], one possible answer is [1, 6, 2, 5, 3, 4]. 解析 摇摆排序 只要奇数位上的数比左右偶数位上的数都大即可 思路 贪心算法:在对问题求解时,总是做…

题目如下: 解题思路:本题和[leetcode]75. Sort Colors类似,但是没有要求在输入数组本身修改,所以难度降低了.引入一个新的数组,然后遍历输入数组,如果数组元素是是偶数,插入到新数组头部,否则追加到尾部. 代码如下: class Solution(object): def sortArrayByParity(self, A): """ :type A: List[int] :rtype: List[int] """ res =…
