problem_description: Statement
  
  In AtCoder city, there are five antennas standing in a straight line. They are
  called Antenna A, B, C, D and E from west to east, and their coordinates are
  a, b, c, d and e, respectively.  
  Two antennas can communicate directly if the distance between them is k or
  less, and they cannot if the distance is greater than k.  
  Determine if there exists a pair of antennas that cannot communicate
  **directly**.  
  Here, assume that the distance between two antennas at coordinates p and q (p
  < q) is q - p.
