import java.io.*;
public class CopyFile
{
public static void main(String args[]) throws Exception
{BufferedReader br=new BufferedReader(new FileReader("shi.txt"));
BufferedWriter bw=new BufferedWriter(new FileWriter("person.txt"));
String s,space=" ";
int num=0;
while(br.ready())
{s=br.readLine();
num++;
bw.writer(String.valueOf(num));
bw.write(space);
bw.write(s);
bw.newLine;
}
bw.close();
}
}
