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>

#include <string.h>
int main(void){
int a,b;   
int yes=0;
scanf("%d %d",&a,&b);
for(int i=a;i<=b;i++){
    if(i/10000==i%10&&i/10%10==i/1000%10){yes++;}
}
printf("%d\n",yes);
}
