import java.util.*;

// define a class

public class MapReduce

{

    // main function

public static void main(String[] args)

   {

       // Perform following process

       Scanner scan= new Scanner(System.in);

       System.out.println("Enter The Statement: ");

       String data= scan.nextLine();

       char array[]= data.toCharArray();

       int num =0;

       for(int x=0;x<array.length;x++)

       {

         if (array[x]==','||array[x]=='.'||array[x]==';'||array[x]=='"'||array[x]==':'){

              num++;

           }

       }

       System.out.println("Number Of Charaers Are: "+num);

   }
