input: def nearest_int(value):
      '''
      Implement a function that accepts a string representing a numeric value
      and returns the nearest integer. In cases where the number is equidistant
      between two integers, the function should round away from zero.
  
      Examples
      >>> nearest_int("10")
      10
      >>> nearest_int("15.3")
      15
  
      Note:
      When rounding away from zero, if the number is right in the middle of two
      integers, choose the integer that is further from zero. For example,
      nearest_int("14.5") should return 15, and nearest_int("-14.5")
      should return -15.
