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.
#Examples:
Kata.getMiddle("test") should return "es"
Kata.getMiddle("testing") should return "t"
Kata.getMiddle("middle") should return "dd"
Kata.getMiddle("A") should return "A"
function getMiddle(s)
{
if (s.length % 2 === 0) {
return s[s.length / 2 - 1] + s[s.length / 2]
}
else {
return s[Math.floor(s.length / 2)]
}
}
