The middle letter

Problem

Write a function that takes a word (with at least one letter) and returns its middle letter: with "sun" you return "u".

If the word has an even number of letters there are two in the middle: return the left one, so with "moon" you return "o".

Examples

• "sun" → "u"

• Even length

  "moon" → "o"

• "chocolate" → "o"

• "computer" → "p"

Besides these, the challenge has hidden tests that are revealed when you submit your solution.

You start with this

def middle_letter(text):
    pass

function middleLetter(text) {
}
