代码的功能：用C语言实现采用三叉链表存储结构实现二叉树的相关操作，如构造、销毁、插入、遍历等功能，代码中带有详细的注解，十分有利于阅读。算法主要优点在于在遍历时减小了时间复杂大。-Functionality of the code: using C language trifurcate linked list storage structure binary tree operations, such as construction, destruction, insert, traversal functions, with detailed comments in the code, very conducive to reading. The algorithm main advantage reduces when the traversal time complexity.
