input_description: Input is given from Standard Input in the following format:
  
      
      
      A B
attempt: a,b=map(int,input().split())
  cnt=0
  for i in range(a,b+1):
      if str(i)　==　str(i)[::-1]:

problem_description: 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.
