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: Accepted)

A, B = map(int, input().split())
cnt = 0
for n in range(A,B+1):
  n_str = str(n)
  n_len = len(n_str)
  is_kaibun = True
  for i in range(n_len//2):
    if n_str[i] != n_str[n_len-1-i]:
      is_kaibun = False
  if is_kaibun is True:
    cnt += 1
print(cnt)

# if n_str[0] == n_str[4] and n_str[1] == n_str[3]:
#   cnt += 1
