loneliest-character

Loneliest character

Complete the function which accepts a string and return an array of character(s) that have the most spaces to their right and left.

Notes:

• the string can have leading/trailing spaces - you should not count them
• the strings contain only unique characters from a to z
• the order of characters in the returned array doesn't matter
