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

#include<stdio.h>
int main()
{
	int i,j,h,g,f,d,a=0,c=0,n,m;
	scanf("%d%d",&n,&m);
	for(i=n;i<m;i++)
	{
		a=0;
		f=i;
		while(f!=0)
		{
			a=a*10+f%10;
			f/=10;
		}
		if(i==a)
		{
			c++;
		}
	}
	printf("%d",c);
	return 0;
