4. What are some common Regex use cases? Regex is commonly used for tasks such as validating user input, searching and replacing text, extracting data from text, and parsing log files.

5. What is the difference between a greedy and non-greedy Regex pattern? A greedy Regex pattern matches the longest possible substring that satisfies the pattern, while a non-greedy pattern matches the shortest possible substring that satisfies the pattern.

6. What is Regex Backtracking? Regex backtracking occurs when a Regex engine tries to match a pattern, but fails at some point, and then tries different combinations of the pattern until a match is found.
