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 num, rem, reverse_num, temp, start, end,cnt=0;
   scanf("%d %d",&start,&end);
   for(num=start;num<=end;num++){
      temp=num;
      reverse_num=0;
      while(temp){
         rem=temp%10;
         temp=temp/10;
         reverse_num=reverse_num*10+rem;
      }
      if(num==reverse_num)
         cnt++;
   }
   printf("%d\n",cnt);
   return 0;
}
