input: def nearest_whole_number(value):
      '''
      Construct a function that accepts a string representation of a number
      and returns the nearest whole number. If the number is equidistant from
      two whole numbers, round it away from zero.
  
      Examples
      >>> nearest_whole_number("10")
      10
      >>> nearest_whole_number("15.3")
      15
  
      Note:
      Rounding away from zero means that if the input number is exactly between
      two whole numbers, the number to return is the one farthest from zero.
      For instance, nearest_whole_number("14.5") should return 15 and
      nearest_whole_number("-14.5") should return -15.
