题目:合并已排序数组 难度:Easy 题目内容: Given two sorted integer arrays nums1 and nums2, merge nums2 into nums1 as one sorted array. 翻译: 给定两个排序的整数数组nums1和nums2,将nums2合并到nums1中作为一个排序数组. 注意: nums1和nums2中初始化的元素数量分别为m和n. nums1有足够的空间(大小大于或等于m+n)来容纳nums2中的额外元素. 我的思路:此处和归…
Given a singly linked list where elements are sorted in ascending order, convert it to a height balanced BST. 由于对于这个二叉搜索树的要求是其必须是其必须是平衡的,所以应该使用递归.首先找到二叉树的中点.然后由这个中点作为根节点递归的在从左右子树上面取节点构成一颗二叉树.代码如下所示: /** * Definition for singly-linked list. * struct L…
题目:合并两个已排序链表 难度:Easy 题目内容: Merge two sorted linked lists and return it as a new list. The new list should be made by splicing together the nodes of the first two lists. 翻译: 合并两个已排序的链表,并将其作为一个新链表返回.新的链表应该通过将前两个列表的节点拼接在一起. Example: Input: 1->2->4, 1-&…
Given two sorted integer arrays nums1 and nums2, merge nums2 into nums1 as one sorted array. Note:You may assume that nums1 has enough space (size that is greater or equal to m + n) to hold additional elements from nums2. The number of elements initi…
Given an array where elements are sorted in ascending order, convert it to a height balanced BST. 讲一个排序好的数组转换成二叉搜索树,这题没想出来,基本上是参考别人的,边界条件应该注意一下: /** * Definition for a binary tree node. * struct TreeNode { * int val; * TreeNode *left; * TreeNode *rig…
题目: Given two sorted integer arrays A and B, merge B into A as one sorted array. Note:You may assume that A has enough space (size that is greater or equal to m + n) to hold additional elements from B. The number of elements initialized in A and B ar…
