input_description: Input is given from Standard Input in the following format:
  
      
      
      S
attempt: S = input()
  print(min(abs(int(S[i:i+3]) - 753)) for i in range(len(S) - 2)
problem_description: Statement
  
  There is a string S consisting of digits `1`, `2`, ..., `9`. Lunlun, the
  Dachshund, will take out three consecutive digits from S, treat them as a
  single integer X and bring it to her master. (She cannot rearrange the
  digits.)
  
  The master's favorite number is 753. The closer to this number, the better.
  What is the minimum possible (absolute) difference between X and 753?
