思路: 1. 空间复杂度为 o(n) 解法. 创建两个链表, 分别记录大于 x 和小于 x 的节点, 最后合并 2. o(1) 的空间复杂度解法. 四个指针, 分别指向小于 x 部分链表的头, 尾, 指向大于 x 部分链表的头, 尾 总结: 1. 使用 dummyNode 减少判断 ...

Given a binary tree with n nodes, your task is to check if it's possible to partition the tree to two trees which have the equal sum of values ...
Given a singly linked list L: L 0→L 1→…→L n-1→L n,reorder it to: L 0→L n →L 1→L n-1→L 2→L n-2→… You must do this in-place without altering the nodes ...
Given a list, rotate the list to the right by k places, where k is non-negative. For example:Given 1->2->3->4->5->NULL and k ...
1. 链表 数组是一种顺序表,index与value之间是一种顺序映射,以\(O(1)\)的复杂度访问数据元素。但是,若要在表的中间部分插入(或删除)某一个元素时,需要将后续的数据元素进行移动,复杂度大概为\(O(n)\)。链表(Linked List)是一种链式表,克服了上述的缺点,插入和删除 ...
