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.

7. What is Regex Lookahead and Lookbehind? Regex Lookahead and Lookbehind are called lookaround, and they allow you to specify a pattern to match only if a certain condition is met ahead or behind the pattern.

8. What is Regex Character Class? Regex Character Class is a set of characters that can be used to match a single character from a given set of characters. For example, [a-z] matches any lowercase letter in the English alphabet.
