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

    int A = sc.nextInt();
    int B = sc.nextInt();
    int count = 0;
    
    for(int i = A; i <= B; i++){
    	int a = i / 10000;
        int b = i % 10;
        if(a != b) continue;
      	a = (i / 1000)% 10;
        b = (i / 10) % 10;
        if(a == b) count++;
    }
    System.out.println(count);
  }
