在采用链式存储结构的二叉树上，以bt指向根结点，p指向任一给定的结点，编程实现求出从根结点到给定结点之间的路径。主要是对二叉树的存储结构及其在二叉链表树上的各种操作加深理解。-The introduction of chain stores on the binary tree structure to point to the root bt, p point to any given node, programming derived from the root to the given path between nodes. Mainly on the binary tree structure and stored in the binary tree list to deepen understanding of various operations.
