List storage structure based on binary tree of basic operations, require: ⑴ to establish a non-empty binary tree ⑵ binary tree prior, during and after order recursive traversal algorithm ⑶ first to achieve non-recursive binary tree (or middle or rear) preorder traversal algorithms and sequence algorithm ⑷ record operating results and non-recursive and recursive algorithm to analyze the efficiency of the algorithm.
