// You are going to be given a word. Your job is to return the middle character of the word. If the word's length is odd, return the middle character. If the word's length is even, return the middle 2 characters.

// Kata.getMiddle("test") should return "es"

// Kata.getMiddle("testing") should return "t"

// Kata.getMiddle("middle") should return "dd"

// Kata.getMiddle("A") should return "A"
