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 C (GCC 5.4.1) (judge verdict: Accepted)

#include <stdio.h>
int main(){
	int i,a,b,l,m,n,o,co=0;
	scanf("%d%d",&a,&b);
	for(i=a;i<=b;i++){
		int o=i%10,n=(i%100-o)/10;
		int l=i/10000,m=(i/1000)%10;
		if(l==o&&m==n)co++;
	}
	printf("%d\n",co);
	return 0;
