Binary search trees have one important property: everything in the left subtree is smaller than the current node, and everything in the right subtree is larger. This lets us look things up in O(lg(n)) time (as long as the tree is balanced).

travel(tree.rchild) //对右孩子递归调用 } } 递归遍历二叉树可以参考递归函数的定义与实现部分的内容: 1递归函数 recursive function :输出正整数N各个位上的数字 2 还可以参考后面启动代码里面的其他已经实现的递归函数,二叉树的很多操作都是通过递归函数实现的。
线索二叉树(Threaded Binary Tree)是在普通二叉树的基础上添加了线索(thread)的数据结构,通过线索将一些空闲的指针域利用起来。线索二叉树的线索分为前序线索、中序线索和后序线索,分别对应着在遍历过程中,指针的前驱和后继关系。通过线索化,可以方便地实现二叉树的遍历操作,提高了遍历效率。在线索二叉树中,每个节点...
