input: def nearest_integer(value):
      '''
      Write a function that accepts a value (string) that represents a number
      and returns the nearest integer to it. If the value is exactly between
      two integers, it should round away from zero.
  
      Examples
      >>> nearest_integer("10")
      10
      >>> nearest_integer("15.3")
      15
  
      Note:
      Rounding away from zero means that if the number is equidistant
      from two integers, you should return the one farther from zero. For example,
      nearest_integer("14.5") should return 15 and nearest_integer("-14.5") should return -15.

output:     value = float(value)
      if value > 0:
          return int(value + 0.5)
      else:
          return int(value - 0.5)
