It seems to me that the Example 1 expected output is not in alphabetical order.

Quoting from Example 1:

• Input: Products: ["apple", "apricot", "application"], searchWord: "app"
• Expected Output: [["apple", "apricot", "application"], ["apple", "apricot", "application"], ["apple", "application"]]

The problem is that "apricot" comes after "application" when sorted alphabetically since the third character of "apricot" is "r" while the third character of "application" is "p" and "r" comes after "p".

So the expected output should actually be: [["apple", "application", "apricot" ], ["apple", "application", "apricot" ], ["apple", "application"]].

Please correct me if I'm mistaken.
