本文介绍了一种将两个已排序的链表合并为一个新排序链表的方法。提供了两种实现思路：一种是通过循环逐个比较节点并构建新链表；另一种是采用递归方式解决。这两种方法都能有效地完成链表的合并。

题目大意：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.

分析：第一种方法可以直接new一个新的链表，对两个链表同时进行循环，比较两个链表头指针的元素大小，小的加到新链表。第二种方法可以使用递归求解。

题目大意：将一个有序链表转化为一颗平衡二叉树题目分析：用递归和二分实现，可以将创建树的过程视为中序遍历一棵树的逆过程（链表即为中序遍历二叉树的结果。）。中序遍历时，首先要访问最左下的叶节点，那就首先创建该节点，然后创建它的父节点，再创建它的兄弟右节点。注意：要首先求出链表的长度，以便于二分地递归。
