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 (3.8.2) (judge verdict: Accepted)

lst = input().split()

count = 0

def judge(n):
   if str(n) == str(n)[::-1]:
      return True
   else:
      return False

for i in range(int(lst[0]), int(lst[1]) + 1):
   if judge(i):
      count += 1

print(count)
