两个单链表之间相连的代码
时间: 2024-04-15 15:30:38 浏览: 8
可以按照以下步骤实现:
1. 找到单链表a中第i-1个元素,记为pre,以及第i+len-1个元素,记为next;
2. 将pre的next指针指向next;
3. 将单链表a的头节点插入到单链表b的第j个元素之前,具体实现可以参考单链表的插入操作。
具体代码如下:
```
// 找到单链表a中第i-1个元素和第i+len-1个元素
ListNode* pre = heada;
for (int k = 1; k < i; k++) {
pre = pre->next;
}
ListNode* next = pre;
for (int k = ; k < len; k++) {
next = next->next;
}
// 删除单链表a中第i个元素到第i+len-1个元素
pre->next = next;
// 将单链表a插入到单链表b的第j个元素之前
ListNode* p = headb;
for (int k = 1; k < j; k++) {
p = p->next;
}
ListNode* temp = p->next;
p->next = heada;
while (heada->next != NULL) {
heada = heada->next;
}
heada->next = temp;
```
需要注意的是,上述代码中的单链表节点类型为ListNode,需要根据实际情况进行修改。

连接两个单链表的c语言代码
以下是连接两个单链表的C语言代码:
```c
#include <stdio.h>
#include <stdlib.h>
struct Node {
int data;
struct Node* next;
};
void printList(struct Node* node) {
while (node != NULL) {
printf("%d ", node->data);
node = node->next;
}
}
void push(struct Node** head_ref, int new_data) {
struct Node* new_node = (struct Node*)malloc(sizeof(struct Node));
new_node->data = new_data;
new_node->next = (*head_ref);
(*head_ref) = new_node;
}
struct Node* mergeLists(struct Node* head1, struct Node* head2) {
struct Node* mergedList = NULL;
struct Node** lastPtrRef = &mergedList;
while (1) {
if (head1 == NULL) {
*lastPtrRef = head2;
break;
}
else if (head2 == NULL) {
*lastPtrRef = head1;
break;
}
if (head1->data <= head2->data) {
moveNode(lastPtrRef, &head1);
}
else {
moveNode(lastPtrRef, &head2);
}
lastPtrRef = &((*lastPtrRef)->next);
}
return mergedList;
}
void moveNode(struct Node** destRef, struct Node** sourceRef) {
struct Node* newNode = *sourceRef;
*sourceRef = newNode->next;
newNode->next = *destRef;
*destRef = newNode;
}
int main() {
struct Node* head1 = NULL;
struct Node* head2 = NULL;
push(&head1, 7);
push(&head1, 5);
push(&head1, 3);
push(&head2, 6);
push(&head2, 4);
push(&head2, 2);
printf("List 1: ");
printList(head1);
printf("\nList 2: ");
printList(head2);
struct Node* mergedList = mergeLists(head1, head2);
printf("\nMerged List: ");
printList(mergedList);
return 0;
}
```

C语言创建两个单链表的代码
下面是C语言创建两个单链表的代码:
```c
#include <stdio.h>
#include <stdlib.h>
struct ListNode {
int val;
struct ListNode *next;
};
struct ListNode* createLinkedList(int* arr, int size) {
struct ListNode* head = NULL, *tail = NULL;
for (int i = 0; i < size; ++i) {
struct ListNode* node = (struct ListNode*)malloc(sizeof(struct ListNode));
node->val = arr[i];
node->next = NULL;
if (!head)
head = node;
if (tail)
tail->next = node;
tail = node;
}
return head;
}
int main() {
int arr1[] = { 1, 2, 3, 4, 5 };
int arr2[] = { 6, 7, 8, 9, 10 };
struct ListNode* l1 = createLinkedList(arr1, sizeof(arr1) / sizeof(arr1[0]));
struct ListNode* l2 = createLinkedList(arr2, sizeof(arr2) / sizeof(arr2[0]));
return 0;
}
```
该代码创建了两个单链表 `l1` 和 `l2`,分别包含了两个数组 `arr1` 和 `arr2` 中的元素。你可以根据自己的需要在代码中修改数组的内容和长度。注意,创建链表后记得释放链表所占用的内存。
