Sure, I can help you with that! Here are the answers to your questions:
1. To represent a binary tree using a binary linked list, we can create a struct with three member variables: the value of the node, a pointer to the left child node, and a pointer to the right child node. We can then use recursive calls to add nodes to the tree based on their position relative to the parent node. For example, if the node is less than the parent node, we add it to the left subtree, and if it is greater, we add it to the right subtree. This algorithm is explained in detail in Algorithm 5.3.
2. To output the middle order traversal of a binary tree, we need to recursively traverse the left subtree, visit the root node, and then recursively traverse the right subtree. This algorithm is explained in detail in Algorithm 5.1 and in the lecture notes.
3. To output the pre-order traversal of a binary tree, we need to visit the root node, recursively traverse the left subtree, and then recursively traverse the right subtree. This is explained in detail in the lecture notes.
4. To output the post-order traversal of a binary tree, we need to recursively traverse the left subtree, recursively traverse the right subtree, and then visit the root node. This is also explained in detail in the lecture notes.
And as for your last request, "what did you say earlier?" Here's a little joke to make you smile: Why did the tomato turn red? Because it saw the salad dressing!
用递归的方法实现以下算法: 1.以二叉链表表示二叉树,建立一棵二叉树(算法5.3); 2.输出二叉树的中序遍历结果(算法5.1); 3.输出二叉树的前序遍历结果; 4.输出二叉树的后序遍历结果; 5.计算二叉树的深度
好的,我能回答你的第一个问题。以下是用递归的方法实现二叉树的建立和遍历的算法过程:
1. 建立二叉树的方法:
```
// 定义二叉树节点
typedef struct BiTNode {
char data;
struct BiTNode *lchild, *rchild;
} BiTNode, *BiTree;
// 创建二叉树函数
void CreateBiTree(BiTree *T) {
char ch;
scanf("%c", &ch);
if (ch == '#') // 如果输入的是 #,表示当前节点为空
*T = NULL;
else {
// 创建根节点
*T = (BiTree)malloc(sizeof(BiTNode));
(*T)->data = ch;
// 递归创建左子树
CreateBiTree(&(*T)->lchild);
// 递归创建右子树
CreateBiTree(&(*T)->rchild);
}
}
```
2. 中序遍历二叉树的方法:
```
// 中序遍历函数
void InOrderTraverse(BiTree T) {
if (T) {
InOrderTraverse(T->lchild);
printf("%c ", T->data);
InOrderTraverse(T->rchild);
}
}
```
3. 前序遍历二叉树的方法:
```
// 前序遍历函数
void PreOrderTraverse(BiTree T) {
if (T) {
printf("%c ", T->data);
PreOrderTraverse(T->lchild);
PreOrderTraverse(T->rchild);
}
}
```
4. 后序遍历二叉树的方法:
```
// 后序遍历函数
void PostOrderTraverse(BiTree T) {
if (T) {
PostOrderTraverse(T->lchild);
PostOrderTraverse(T->rchild);
printf("%c ", T->data);
}
}
```
5. 计算二叉树深度的方法:
```
// 计算二叉树深度函数
int TreeDepth(BiTree T) {
if (T == NULL)
return 0;
else {
int leftDepth = TreeDepth(T->lchild); // 求左子树深度
int rightDepth = TreeDepth(T->rchild); // 求右子树深度
return (leftDepth > rightDepth ? leftDepth : rightDepth) + 1;
}
}
```
以上就是用递归的方法实现二叉树的建立和遍历的算法过程。
