🔗 Getting the Middle Character

Write a function, solution, that returns the middle character of a word s. If the word's length is even, return the two middle characters.

• s is a string with a length between 1 and 100.

A simple problem: given a string s, return its middle character. However, if the length is even, return two characters.

Determine the length of s to check whether it's odd or even. If it's odd, return one middle character; if even, return two.
