        int status = 1;
        int score = 0;
        int centerCount = 0;
        Scanner scan = new Scanner(System.in);
        
        while(true) {
            status = scan.nextInt();
            if(status == 1) {
                score+=1;
                centerCount=0;
            }
            else if(status ==2) {
                centerCount+=1;
                score+=(centerCount*2);
            }
            else
                break;
                
        }
        
        System.out.println(score);
    }

}

主类名称改为Main
