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

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

Sample Input 2

31415 92653

Sample Output 2

612

Solution in PHP (5.6.30) (judge verdict: Accepted)

<?php
// Your code here!
$input = explode(" ",trim(fgets(STDIN)));
$min = $input[0];
$max = $input[1];
$count = 0;

for($i=$min;$i<=$max;$i++){//
    $judge = str_split($i);
    if($judge[0] == $judge[4] && $judge[1] == $judge[3]){
        $count++;
    }
}

echo $count;

?>
