C++ Find Min and Max element in a BST
对于一个二叉搜索树, 要想找到这棵树的最小元素值, 我们只需要从树根开始, 沿着left 孩子指针一直走, 知道遇到NULL(即走到了叶子), 那么这个叶子节点就存储了这棵二叉搜索树的最小元素。 同理, 从根节点开始, 沿着right 孩子指针, 最终找到的是最大关键字的节点。  也就是说寻找BST最小关键字的元素和最大关键字的元素的代码是对称的。伪代码如下: TREE_MINIMUM(x...

二叉排序树(BST)
二叉排序树: 二叉排序树(Binary Sort Tree)又称二叉查找树(Binary Search Tree),亦称二叉搜索树。 它或者是一棵空树;或者是具有下列性质的二叉树: (1)若左子树不空,则左子树上所有结点的值均小于它的根结点的值; (2)若右子树不空,则右子树上所有结点的值均大于它的根结点的值; (3)左、右子树也分别为二叉排序树; 注:中序遍历一棵二叉排序...
