import java.util.Scanner;

public class PartOfString {
   public static void main(String[] args) {
       Scanner sc = new Scanner(System.in);
       System.out.print("Enter a string: ");
       String str = sc.next();
       System.out.print("Enter number of characters to display: ");
       int n = sc.nextInt();
       if (str.length() < n) {
           System.out.println("Error The requested size is too large!");
           return;
       }
       System.out.println("Enter first or last: ");
       String s = sc.next();
      
       if (s.equalsIgnoreCase("first")) {
           System.out.println("The first " + n + " letters are " + str.substring(0, n));
       } else {
           System.out.println("The last " + n + " letters are " + str.substring(str.length() - n));
       }
   }
