Complete the function which accepts a string and returns 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

Examples

"a b  c"                        -->  ['b']
"a bcs           d k"           -->  ['d']
"    a b  sc     p     t   k"   -->  ['p']
"a  b  c  de"                   -->  ['b', 'c']
"     a  b  c de        "       -->  ['b']
"abc"                           -->  ['a', 'b', 'c']

Good luck!
