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())
a1 = a//100
b1 = b//100
a2 = a//1000
b2 = b//1000
a3 = ((a2)%10)*10 + (a2%100)//10
b3 = ((b2)%10)*10 + (b2%100)//10
a4 = a%100
b4 = b%100
count = 0
if a3 >= a4:
    count = count + 1
if b3 <= b4:
    count = count + 1
if b1 - a1 == 0:
    if count == 2:
        print(1)
    else:
        print(0)
else:
    print(b1-a1+count)
