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

Solution in JavaScript (node.js v5.12) (judge verdict: Accepted)

inp = require('fs').readFileSync('/dev/stdin', 'utf8').trim().split('\n')
l = inp.shift().split(' ')
A = l[0] - 0
B = l[1] - 0
cnt = 0
for (i=A; i<=B; i++) {
    s = i+''
    if (s[0] == s[4] && s[1] == s[3]) {
        cnt++
    }
}
console.log(cnt)
