I got leetcode (3076. Shortest Uncommon Substring in an Array) with different form of input
and output was expected in different way.
eg
// star_wars_titles = [
// 'The Phantom Menace',
// 'Attack of the Clones',
// 'Revenge of the Sith',
// 'A New Hope',
// 'The Empire Strikes Back',
// 'The Return of the Jedi',
// 'The Force Awakens',
// 'The Last Jedi',
// ]

// Then the smallest unique substring you could type in to specify each is:

// {
// 'The Phantom Menace': 'to',
// 'Attack of the Clones': 'tt',
// 'Revenge of the Sith': 'v',
// 'A New Hope': 'ho',
// 'The Empire Strikes Back': 'b',
// 'The Return of the Jedi': 'u',
// 'The Force Awakens': 'aw',
// 'The Last Jedi': 'tj',
// }
