模拟加法过程即可。

 

AC代码:

 1 import java.io.BufferedReader;
 2 import java.io.IOException;
 3 import java.io.InputStreamReader;
 4 
 5 public class Main {
 6     
 7     public static void main(String[] args) throws NumberFormatException, IOException {
 8         
 9         BufferedReader reader=new BufferedReader(new InputStreamReader(System.in));
10         
11         boolean first=true;
12         while(first || reader.ready()){
13             first=false;
14             String ss[]=reader.readLine().split(" ");
15             int a=Integer.parseInt(ss[0]);
16             int b=Integer.parseInt(ss[1]);
17             if(a==0 && b==0) return ;
18             System.out.println(solve(a,b));
19         }
20         
21     }
22     
23     public static int solve(int a,int b){
24         int res=0; boolean carry=false;
25         while(a>0 && b>0){
26             int t1=a%10;
27             int t2=b%10;
28             if(t1+t2+(carry?1:0)>=10){
29                 res++;
30                 carry=true;
31             }else{
32                 carry=false;
33             }
34             a/=10;
35             b/=10;
36         }
