  getMiddle("testing") should return "t"
  getMiddle("middle") should return "dd"
  getMiddle("A") should return "A"

  const odd_even = s.length % 2
  const division = odd_even === 0 ? s.length / 2 : (s.length - 1) / 2
  return s.length === 1 ? s 
  	: odd_even === 0 ? s.substr(division - 1, 2) 
  	: s.substr(division, 1)
