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: Wrong Answer)

#include<stdio.h>
int main(){
  int a,b,g=0;
  scanf("%d %d",&a,&b);
  for(int i=a; i<=b; i++){
    int c,d,e,f;
    c=a/10000;d=a%10;
    a%=10000;a/=10;
    e=a/100;f=a%10;
    if(c==d&&e==f){g++;}
  }
  printf("%d",g);
  return 0;}
