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)

import math

A, B = map(int, input().split())
flag = True
count = B-A+1
for i in range(A, B+1):
    for j in range(int(math.ceil(len(str(A)))/2)):
        if str(i)[j] != str(i)[-1-j]:
            count -= 1
            break
print(count)
