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.*;

class Main{
	
	public static void main(String[] args){
		Scanner sc = new Scanner(System.in);
		
		int A = sc.nextInt();
		int B = sc.nextInt();
		//5桁回文数→  1桁目=5桁目 かつ 2桁目=4桁目
		
		int count = 0 ;
		for(int i = A ; i <= B ;i ++){
			if( i/10000 == ( i % 10 ) && ( i /1000 ) % 10 == ( i /10 ) % 10 ){
				
				count ++;
			}
		}
		System.out.println(count);
