Now, we know what is balance factor of the node in the AVL tree is. Let’s see an example of an AVL tree in data structure with a balance factor for each node. In the above example, we can say the above binary

AVL Tree Datastructure AVL tree is a height-balanced binary search tree. That means, an AVL tree is also a binary search tree but it is a balanced tree. A binary tree is said to be balanced if, the difference between the heights of left and right subtrees of every node in the tree...

这是目前难度最高的一个作业,主要难点在于树的平衡,树的平衡依赖于调试输出的图形化,也就是输出二叉树的实现,二叉树的输出技巧性比较强,一般人很难直接想到控制台可以打印二叉树。后面的测试结果显示本文实现的AVLTree 4次战胜std::map。 平衡部分的调试最好用很少很少量的数据,把各种情况跑一遍,因为一旦不考虑测...
