Remove any word that does not start with a capital letter. For instance, for the input text of "Hello, 2022 world!", we should get "Hello, 2022 !". Notes: As in the previous question, you can safely assume that the set of characters that will be used will be only among the following: alphabetical characters [A-Za-z] (upper and lower case English letters), numerics [0-9] (digits), the space character [ ], and the following 6 punctuations: [.,!?;:]. You can define a word as follows: starts with a letter [A-Za-z], then proceeds with alphanumeric characters [A-Za-z0-9] until hits a non alphanumeric character (so a space character or a punctuation). However, if for simplicity, you take each word to be allowed to start with numeric characters too, that is fine as well (your outputs will be considered as valid). So for instance, the words like 2way, 4door, etc or even numbers like 2022 are also valid words.
