java解法
利用ArrayList类型，模拟队列

import java.util.*;
public class Main {
        public static int rev(int x){
            ArrayList<Integer> numList=new ArrayList<>();
            while(true){
                if(x/10!=0){
                    numList.add(x%10);
                    x=x/10;
                }else{
                    numList.add(x);
                    break;
                }                
            }
            int all=0;
            for(int i=0;i<numList.size();i++){
                all=all*10+numList.get(i);
            }

            return all;
        }

    public static void main(String[] args){
        Scanner sc=new Scanner(System.in);
        int x=sc.nextInt();
        int y=sc.nextInt();
        System.out.println(rev(rev(x)+rev(y)));
    }
}
