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 = list(map(int,input().split()))
count = 0
for i in range(A,B+1):
  x = i
  a1 = x//10000
  x = x - 10000*a1
  a2 = x//1000
  x = x - 1000*a2
  a3 = x//100
  x = x - 100*a3
  a4 = x//10
  a5 = x - 10*a4
  if a1 == a5 and a2 == a4:
    count +=1
    
print(count)
