在C语言中,如果你想要实现两个集合A和B的交集,并将结果存储在另一个链表C中,你可以采用以下步骤:
1. 定义链表节点结构:
```c
typedef struct Node {
int value;
struct Node* next;
} Node;
```
2. 初始化链表:
```c
Node* createEmptySet() {
Node* newNode = (Node*)malloc(sizeof(Node));
newNode->value = 0;
newNode->next = NULL;
return newNode;
}
// 创建链表A和B
Node* setA = createEmptySet(); // ... 添加A集合元素
Node* setB = createEmptySet(); // ... 添加B集合元素
```
3. 查找交集并插入到链表C:
```c
Node* findIntersection(Node* setA, Node* setB, Node* resultSet) {
if (!setA || !setB) return resultSet; // 空集无交集
Node* currA = setA;
Node* currB = setB;
Node* currResult = resultSet;
while (currA && currB) {
if (currA->value == currB->value) {
if (currResult == NULL) { // 初始化结果集
currResult = createEmptySet();
currResult->value = currA->value;
currResult->next = resultSet;
resultSet = currResult;
} else {
// 结果集中已存在该元素,跳过
currA = currA->next;
currB = currB->next;
}
} else if (currA->value < currB->value) {
currA = currA->next;
} else {
currB = currB->next;
}
}
return resultSet;
}
```
4. 清理和显示结果集:
```c
void displaySet(Node* set) {
while (set) {
printf("%d ", set->value);
set = set->next;
}
printf("\n");
}
// 使用结果集
displaySet(findIntersection(setA, setB, NULL)); // 输出交集
```
