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 = [int(x) for x in input().split()]

def main():
    count = 0
    for num in range(A, B + 1):
        s = str(num)
        pri = s[0:3] # first 3 chars
        sec = s[4:1:-1] # last 3 chars
        if pri == sec:
            count += 1
    print(count)

if __name__ == "__main__":
    main()
