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)

function Main(input){
  var tmp = input.split(' ');
  var count = 0;
  for(var i=Number(tmp[0]);i<=Number(tmp[1]);i++){
    count += check(i);
  }
  function check(num){
    var str = String(num);
    var cut = str.substr(Math.ceil(str.length/2)).split('').reverse().join('');
    for(var i=0;i<cut.length;i++){
      if(str[i]!=cut[i]){
        return 0;
      }
    }
    return 1;
  }
  console.log(count);
}
Main(require("fs").readFileSync("/dev/stdin", "utf8"));
