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

		Scanner scanner = new Scanner(System.in);
		Integer output = 0;
		Integer aInteger = new Integer(scanner.next());
		Integer bInteger = new Integer(scanner.next());

		StringBuffer buffer ;
		for(int i = aInteger; i <= bInteger;i++ ) {
			buffer = new StringBuffer(String.valueOf(i));
			if(String.valueOf(i).compareTo(String.valueOf(buffer.reverse()))==0) {
				output++;
			}
		}
		System.out.println(output);
		scanner.close();
