实现ADT,可以实现两个二叉树的几种逻辑关系来显示它们之间的联系.如:求两个二叉树是否是等价的.它们的交集并集是怎样的.等等.这样这些都是ADT要实现的方法.-achieve ADT, can achieve two binary tree several logical relationship to show the linkages between them. Such as : whether the binary tree for two are synonymous. The intersection of what is the set. And so on. ADT then these are the methods to achieve.
