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 (2.7.6) (judge verdict: Accepted)

n = []
n = map(int, raw_input().split(" "))
ans = 0
for i in range(n[0],n[1]+1):
	if str(i)[0] == str(i)[-1] and str(i)[1] == str(i)[-2]:
		ans += 1
print ans
