problem_description: Statement
  
  Two students of AtCoder Kindergarten are fighting over candy packs.
  
  There are three candy packs, each of which contains a, b, and c candies,
  respectively.
  
  Teacher Evi is trying to distribute the packs between the two students so that
  each student gets the same number of candies. Determine whether it is
  possible.
  
  Note that Evi cannot take candies out of the packs, and the whole contents of
  each pack must be given to one of the students.
