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 Kotlin (1.0.0) (judge verdict: Accepted)

fun main(args:Array<String>){
  var (a,b) = readLine()!!.split(" ").map(String::toInt)
  var count = 0
  for(i in a..b){
    var arr = i.toString().toCharArray()
    if(arr[0]==arr[4] && arr[1]==arr[3]){
      count++
    }
  }
  println(count)
}
