            int x, i;
            String st;
            System.out.print("Inputkan kata atau kalimat : ");
            st = entri.readLine();
          
            x = st.length();
            for (i=0;i<x;i++)
            {
                if(i==0)
                    System.out.println("Huruf awal : "+st.charAt(i));
                if(i==x-1)
                    System.out.println("Huruf akhir: "+st.charAt(i));
            }
          
            System.out.print("Kata setelah dibalik : ");
            for (i=x-1;i>=0;i--)
            {
