According to the abstract data type binary definition, use two forks to implement a binary tree list. The basic function of a binary tree: 1, build the binary tree 2, 3, before traversing a binary tree, binary tree traversal in the order 4, 5, after traversing a binary tree, binary tree traversal according to the sequence 6, find binary tree of depth 7, find the specified path to the root node 8, the destruction of binary tree
