import java.io.*;

public class count
{
public static void main(String args[])
{

int i=0;
String s;
try
{

BufferedReader b2= new BufferedReader(new FileReader("2.txt"));
while((s=b2.readLine())!=null)
{
System.out.println(s);
for(int j=0;j<s.length();j++)
{
if(s.charAt(j)>=97 && s.charAt(j)<=122)
System.out.println(i+=s.length());
}
}
b2.close();
}
catch(IOException o)
{
o.printStackTrace();
