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 <bits/stdc++.h>
using namespace std;
int main(){
  int A,B,L,R;
  cin >> A >> B;
  int x =0;
  for(int N=A;N<=B;N++){
 	L=N/1000;
    R=N%100;
    if(abs(L-R)%11==0)
      x++;
  }
  cout << x << endl;
