You are given two non-empty linked lists representing two non-negative integers. The digits are stored in reverse order and each of their nodes contain a single digit. Add the two numbers and return it as a linked list. You may assume the two numbers do not contain any leading zero, exc...

Add Two Numbers 方法一: 考虑到有进位的问题,首先想到的思路是: 先分位求总和得到 totalsum,然后再将totalsum按位拆分转成链表; 代码语言:javascript 复制 1ListNode*addTwoNumbers(ListNode*l1,ListNode*l2){2int sum=0;3int i=1;4while(l1!=NULL&&l2!=NULL)5{6sum+=i*(l1->val+l2->val);7i*=10...
30. 31. 32. 33. 34. 35. 36. 37. 总结 通过以上步骤和代码示例,你应该能够理解如何在Java中实现LeetCode上的Add Two Numbers问题了。记住,代码编写过程中要注意细节,特别是对空指针的处理和进位的考虑。继续学习,不断提升自己的编程技能,加油!
