// Examples:

// ('Buy a !car [!red green !white] [cheap or !new]')  =>  ['Buy', 'a', '!car', '[!red green !white]', '[cheap or !new]']
// ('!Learning !javascript is [a joy]')                =>  ['!Learning', '!javascript', 'is', '[a joy]']

const cleverSplit = (s) => {
  // Regular expression pattern to match words, exclamation marks, and sets
  const pattern = /\[.*?\]|\S+/g;

  // Find all matches using the pattern
  const matches = s.match(pattern);
