input_description: Input is given from Standard Input in the following format:
  
      
      
      N
attempt: s=input();if(s[0]==s[2] and s[0]<s[1])
problem_description: Statement
  
  You are given a three-digit positive integer N.  
  Determine whether N is a _palindromic number_.  
  Here, a palindromic number is an integer that reads the same backward as
  forward in decimal notation.
samples: [{"input": "575", "output": "Yes\n    \n\nN=575 is also 575 when read backward, so it is a palindromic number. You\nshould print `Yes`.\n\n* * *"}, {"input": "123", "output": "No\n    \n\nN=123 becomes 321 when read backward, so it is not a palindromic number. You\nshould print `No`.\n\n* * *"}, {"input": "812", "output": "No"}]
