        for(i=0;i<3;i++) sum[i]=0;
        while(copy){
            sum[0]=sum[0]+copy%10;
            copy=copy/10; 
        }
        copy=num;
        while(copy){

        }
        copy=num;
        while(copy){
            sum[2]=sum[2]+copy%12;
            copy=copy/12;
        }
        if(sum[0]==sum[1]&&sum[1]==sum[2]) cout<<num<<endl;
        num++;
