        BufferedReader br = new BufferedReader(in);
        System.out.print("Enter the string: ");
        String s = br.readLine();
        String t = new String();
        int len = s.length();
        for(int i = 0; i < len; i++){
            char ch = s.charAt(i);
            t += ch;
            while(i + 1 < len && s.charAt(i + 1) == ch)
                i++;
        }
        System.out.println(t);
    }
