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 Python (3.4.3) (judge verdict: Wrong Answer)

n, m = map(int, input().split())

if n==1 and m==1:
  print(1)
elif n==1 or m==1:
  c = max(0, m-2)
  d = max(c, n-2)
  print(d)
else:
  print((n-2)*(m-2))
