八 方块移动游戏要求从一个含8个数字（用1-8表示）的方块以及一个空格方块（用0表示）的3x3矩阵的起始状态开始，不断移动该空格方块以使其和相邻的方 块互换，直至达到所定义的目标状态。空格方块在中间位置时有上、下、左、右4个方向可移动，在四个角落上有2个方向可移动，在其他位置上有3个方向可移 动。例如，假设一个3x3矩阵的初始状态为： 8 0 3 2 1 4 7 6 5 目标状态为： 1 2 3 8 0 4 7 6 5-Eight-box requirements of mobile games from one containing eight numbers (1-8 with express) the box, as well as a space box (with 0) of the 3x3 matrix of the initial start, and constantly move the box to make space its adjacent box and swap until they reach their defined target state. Spaces in the middle position box has the upper and lower, left and right direction of four removable, in the four corners there are two directions can be mobile, in other locations has three movable direction. For example, suppose a 3x3 matrix of the initial state as follows: 803,214,765 target state as follows: 123,804,765

1.[问题描述] 编写递归算法，计算二叉树中叶子结点的数目 [输入] 按照先序序列的顺序输入该结点的内容。其输入abd eh cf i g . [输出] 按中序序列输出，输出的结果为；dbheaficg并计算出二叉树中叶子结点的数目为4 [存储结构] 采用二叉表存储 [算法的基本思想] 采用递归方法建立和遍历二叉树。首先建立二叉树的根结点，然后建立其左右子树，直到空子树为止，中序遍历二叉树时，先遍厉左子树，后遍厉右子树，最后访问根结点。根据左右子树的最后一个结点计算出二叉树中叶子结点的数目。 程序如下： #include #include #include"stdlib.h" -1. [Description of the issue] to prepare recursive algorithm, Binary calculation leaves the number of nodes [imported] in accordance with the first order input sequence in the order of the node contents. Input abd eh i g cf. [Output] by the order sequence output, the results of the output; dbheaficg calculated Binary leaf node to the number four [storage structure] Table 2 forks storage [ The basic idea algorithm] recursive method and traverse binary tree. First established binary tree root node, and then to build their son around the tree, the tree until the loopholes, which preorder binary tree, Li first times the left sub-tree, right af
