中国建设银行e路通网站厦门软件开发工资一般多少

第一个是测试用例代码，测试的是两个带头的逆序链表相加，并且有反转操作

但是题目要求的是不带头链表直接相加，不需要逆转，输出结果也是逆序的，

题解放在第二个代码中

#include<stdio.h>
#include<stdlib.h>

}
struct ListNode* addTwoNumbers(struct ListNode* l1, struct ListNode* l2) {List*L1=reverse(l1);L1->val = 0;List*L2=reverse(l2);L2->val = 0;List* L3 = (List*)(malloc)(sizeof(List));L3->next = NULL;L3->val = 0;int flag = 0;while (L1 != NULL || L2 != NULL) {List* temp = (List*)(malloc)(sizeof(List));temp->next = NULL;temp->val = 0;if (L1) {temp->val += L1->val;L1 = L1->next;}if (L2) {temp->val += L2->val;L2 = L2->next;}if (flag == 1) {temp->val += 1;flag = 0;}//进位if (temp->val >= 10) {temp->val= temp->val % 10;flag = 1;}//大于10进位List* cur = L3;while (cur->next != NULL) {cur = cur->next;}cur->next = temp;if (L1 == NULL && L2 == NULL && flag == 1) {List* digital = (List*)(malloc)(sizeof(List));digital->val = 1;digital->next = NULL;temp->next = digital;}}L3->next->val = 0;return reverse(L3->next);
