Add Two Numbers-Java

题目描述：

You are given two linked lists representing two non-negative numbers. 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.、
百度翻译后（您将得到两个表示两个非负数的链表。数字以相反的顺序存储，每个节点包含一个数字。想加这两个数字，并将其作为链接列表返回。）
例如：
1->2->3->4->5
9->8->7->6
输出：
0->1->1->1->6
（01116）
即54321+6789=61110

代码

import java.util.Scanner;

public class Test {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        String s = scanner.nextLine();
        String s1 = scanner.nextLine();
        int size = s.length();
        if (s1.length() > size) {
            size = s1.length();
        }
        int[] arr = new int[size];
        int[] brr = new int[size];
        for (int i = 0; i < s.length(); i++) {
            arr[i] = Integer.parseInt(s.substring(i, i + 1));
        }
        for (int i = 0; i < s1.length(); i++) {
            brr[i] = Integer.parseInt(s1.substring(i, i + 1));
        }
        int tmp = 0;
        for (int i = 0;i<size;i++){
            int x = arr[i] + brr[i];
            if (tmp == 1) {
                x+=1;
                tmp = 0;
            }
            if (x>=10){
                tmp = 1;
                x -=10;
            }
            System.out.print(x);
        }
    }
}

输出：
