    if(count<100&&count>9)
        st.append("00");
    if(count>99&&count<1000)
        st.append("0");
                             
            
    st.append(count).append("\n");

    }
    System.out.println(st);

}

}

I don’t really understand for the problem code D1 what is my above code not handling. Its getting a wrong answer not a TLE. So its fast enough but I’m not handling a certain case i suppose but I dunno what exactly. Can anyone help?
