We need to print the list in Dictionary form.Hence , We will use TreeSet .
4 steps should be follow:

*     Take the names and add in TreeSet (ts).
*     Print the size of TreeSet. (For total number of names in O/P)
*     Iterate the ts and store the names in StringBuffer (sb) by appending "\n" for new line in Output.
*     Print the StringBuffer sb.

**Note**: *To reduce Time Complexity use StringBuffer . This will be helpful to avoid Partially Accepted Solution.
*
Some test files contain large data and
Time Limit: 1.0 sec(s) for each input file.

Java8 Code:

```
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.util.TreeSet;
import java.util.Iterator;

class TestClass{
    public static void main(String args[] ) throws Exception {
        try{
         BufferedReader s = new BufferedReader(new InputStreamReader(System.in));
        int t=Integer.parseInt( s.readLine());
        TreeSet<String> ts = new TreeSet<>();
        while(t-- != 0){
            ts.add(s.readLine());
        }

System.out.println(ts.size());
        StringBuffer sb = new StringBuffer();
        Iterator itr = ts.iterator();
        while(itr.hasNext()){
            sb.append(itr.next()+"\n");
        }
        System.out.print(sb);
        }
        catch(Exception e){}
        
    }
}

```
