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

package main

import "fmt"

func main() {
        var a, b, count int
        fmt.Scan(&a, &b)
        for i := a; i <= b; i++ {
                if palindromic(i) {
                        count++
                }
        }
        fmt.Printf("%d\n", count)
}

func palindromic(input int) bool {
        tmp := input
        digits := []int{}
        for tmp != 0 {
                digits = append(digits, tmp%10)
                tmp /= 10
        }
        for i := 0; i < len(digits)/2; i++ {
                if digits[i] != digits[len(digits)-1-i] {
                        return false
                }
        }
        return true
