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 check(int x){
	char s[6];
	snprintf(s,6,"%d",x);
	if(s[0]==s[4] && s[1]==s[3]){
		return 1;
	}else{
		return 0;
	}
}
int main(){
	int a,b;
	int i,ans=0;
	scanf("%d%d",&a,&b);
	for(i=a;i<=b;i++){
		if(check(i)==1){
			ans ++;
		}
	}
	printf("%d",ans);
	return 0;
}
