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).

    Scanner sc = new Scanner(System.in);
    int a = sc.nextInt();
    int b = sc.nextInt();
    
    int cou = 0;
    for(int i=a; i<=b; i++) {
    		if(i/10000 == i%10) {
    			if(i/1000-i/10000*10 == (i%100)/10) {
    			cou++;
    		}
    }
    }
    System.out.println(cou);
