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: Runtime Error)

a = input()
b = input()
a_12 = int(a[0:2])
a_3 = int(a[2])
a_45 = int(a[3:5])
b_12 = int(b[0:2])
b_3 = int(b[2])
b_45 = int(b[3:5])
a_21 = int(a[1]+a[0])
b_21 = int(b[1]+b[0])
ans = (b_12-a_12+1)*10 - a_3 - (10 - b_3 - 1)
if a_21 < a_45:
    ans = ans - 1
if b_21 > b_45:
    ans = ans - 1
print(ans)
