Add Two Numbers

两数之和，本位和进位的求和

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, except the number 0 itself.

Example

Input: (2 -> 4 -> 3) + (5 -> 6 -> 4)
Output: 7 -> 0 -> 8
Explanation: 342 + 465 = 807.

/*** Definition for singly-linked list.* public class ListNode {*     int val;*     ListNode next;*     ListNode(int x) { val = x; }* }*/
class Solution {public ListNode addTwoNumbers(ListNode l1, ListNode l2) {if(l1 == null || l2 == null) return null;ListNode sum = new ListNode(0);ListNode node = sum;int num = 0;int carry = 0;while(l1 != null || l2 != null){    if(l1 != null) {num += l1.val;l1 = l1.next;}if(l2 != null) {num += l2.val;l2 = l2.next;}carry = num / 10;node.next = new ListNode(num % 10);node = node.next;num = carry;}if(num != 0) node.next = new ListNode(num);return sum.next;}
}
