Problem Statement

Find the number of palindromic numbers among the integers between A and B (inclusive).
Here, a palindromic number is a positive integer whose string representation in base 10 (without leading zeros) reads the same forward and backward.

Constraints

10000 \leq A \leq B \leq 99999

All input values are integers.

Input

Input is given from Standard Input in the following format:

A B

Output

Print the number of palindromic numbers among the integers between A and B (inclusive).

Sample Input 1

11009 11332

Sample Output 1

4

There are four integers that satisfy the conditions: 11011, 11111, 11211 and 11311.

Sample Input 2

31415 92653

Sample Output 2

612

import java.util.Scanner;

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

      int a, b, numOfPalindromic = 0;
          int[] digit = new int[5];
          Scanner sc = new Scanner(System.in);

          a = sc.nextInt(); b = sc.nextInt();

          for(; a<b; a++){
          	for(int i=0; i<digit.length; i++)
          		digit[i] = (a/(int)Math.pow(10, i)) % 10; // digit[0] = １の位, digit[1] = 10の位 ・・・

          	if (digit[0] == digit[4] &&  digit[1] == digit[3])
          			numOfPalindromic++;
          }

          System.out.println(numOfPalindromic);

    }
