从键盘上输 入一串正整数， 最后输入－1作为输入结束的标志。以这些正整数的值作为二叉排序树中的结点的数据场之值，建立一棵二叉排序树要实现排序二叉树的插入。采取叶子插入法，即新插入的节点均为改二叉树的叶子节点，且满足中序有序性。-From the keyboard to enter a string of positive integers, the last input-1 as the input end of the sign. These are integer values as binary sort tree nodes in the data field" s value, and the establishment of a binary sort tree to achieve binary tree insertion sort. To leaf insertion method, that the new nodes are inserted to change the binary tree leaf node, and in order to meet the orderliness.
