题目:
You are given a binary tree with unique integer values on each node. However, the child pointers on each node may point to any other node in the tree including itself, introducing cycles into the...

引用(references)使用“.”操作符,指针(pointers)使用“*”和“->”操作符,这是两者最基本也是最熟悉的区别了,应该不用详说。
首先,没有所谓的null reference。一个reference必须总代表某个对象,因此C++要求references必须有初值:
string& rs;//错误!references必须被初始化
string s("xyzzy");
st...

题目: 给定一个二叉树(假设是完全二叉树),把每个节点的next指针指向其右侧节点。
思路:首先想到的是,层序遍历树,在遍历的同时添加节点对右侧节点的指针。
另一种简洁的方法是采用递归来实现,间单直观。...
