🧠 Before you code — what pattern fits?
Given an input string s, reverse the order of the words. A word is a maximal substring of non-space characters. Return a string with the words in reverse order joined by a single space, with no leading or trailing spaces.
"the sky is blue" → "blue is sky the"
" hello world " → "world hello"
