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 sum = 0;
	input = input.split(" ").map(Number);
	for(var i=input[0];i<=input[1];i++){
		var n = String(i).split("");
		var p = [];
		for(var k=0;k<n.length;k++){
		    p.push(n[n.length-1-k])
		}
		if(n.join("")==p.join("")) sum++;
	}
	console.log(sum)
}Main(require("fs").readFileSync("/dev/stdin", "utf8").trim());
