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: Wrong Answer)

A,B = map(int,input().split())
count = 0
k = B-A
for j in range(k):
    a = A+j
    a = str(a)
    a = list(a)
    L = len(a)
    flag = 0
    for i in range(int(L/2)):
        if a[i] == a[-i-1]:
            pass
        else:
            flag = 1
            break
    if flag == 0:
        count+=1
print(count)
