二叉树的源代码
二叉树是一种重要的数据结构，它由节点组成，每个节点最多有两个子节点，通常称为左子节点和右子节点。二叉树的概念在计算机科学中广泛应用于搜索、排序、文件系统等领域。本主题将深入探讨如何用源代码实现二叉树的建立、先序、中序、后序遍历，并讨论递归与非递归两种遍历方法。
我们要理解二叉树的基本操作。在C语言中，我们可以创建一个结构体来表示二叉树的节点，包含两个指针（left和right）分别指向左子节点和右子节点，以及一个用于存储数据的字段（如int data）。例如：
```c
typedef struct Node {
int data;
struct Node* left;
struct Node* right;
} Node;
```
接下来，我们将讨论如何构建二叉树。二叉树的构建通常涉及插入新节点。假设我们有一个函数`insertNode(Node** root, int value)`，该函数接受根节点的指针和要插入的值。如果根节点为空，我们就创建一个新的节点作为根；否则，我们根据值的大小决定将其插入左子树还是右子树。
对于遍历，有三种主要的方式：先序遍历、中序遍历和后序遍历。
1. **先序遍历**：访问根节点 -> 遍历左子树 -> 遍历右子树。递归实现如下：
```c
void preOrderTraversal(Node* node) {
if (node == NULL)
return;
printf("%d ", node->data);
preOrderTraversal(node->left);
preOrderTraversal(node->right);
}
```
非递归实现可以使用栈来辅助完成：
```c
void preOrderTraversalNonRecursive(Node* node) {
stack s;
while (node != NULL || !s.empty()) {
while (node != NULL) {
printf("%d ", node->data);
s.push(node);
node = node->left;
}
if (!s.empty()) {
node = s.top();
s.pop();
node = node->right;
}
}
}
```
2. **中序遍历**：遍历左子树 -> 访问根节点 -> 遍历右子树。递归实现：
```c
void inOrderTraversal(Node* node) {
if (node == NULL)
return;
inOrderTraversal(node->left);
printf("%d ", node->data);
inOrderTraversal(node->right);
}
```
非递归实现同样使用栈：
```c
void inOrderTraversalNonRecursive(Node* node) {
stack s;
Node* curr = node;
while (curr != NULL || !s.empty()) {
while (curr != NULL) {
s.push(curr);
curr = curr->left;
}
if (!s.empty()) {
curr = s.top();
s.pop();
printf("%d ", curr->data);
curr = curr->right;
}
}
}
```
3. **后序遍历**：遍历左子树 -> 遍历右子树 -> 访问根节点。递归实现需要借助额外的栈或队列，这里仅展示递归实现：
```c
void postOrderTraversal(Node* node) {
if (node == NULL)
return;
postOrderTraversal(node->left);
postOrderTraversal(node->right);
printf("%d ", node->data);
}
```
非递归实现较为复杂，涉及到访问节点时的标记机制。
在`tree_01.c`文件中，很可能包含了这些功能的实现。通过阅读和理解这段代码，你可以更深入地了解二叉树的构造和遍历。对于二叉树的学习，不仅限于理解和编写代码，还需要理解其背后的逻辑和应用，这有助于提升你在算法和数据结构方面的技能。
