Regular Expressions [Part 2] - Metacharacter Symbols

This video tutorial covers the basics of regular expressions, including the use of literal characters, metacharacter symbols, wildcards, and optional characters. It also explains how to create a custom function to test regular expressions and handle case sensitivity. The tutorial further explores the use of the dot (.) and asterisk (*) as wildcards, the question mark (?) for optional characters, and how to escape characters to use them as literals. The video concludes with a brief introduction to character sets, quantifiers, and grouping, which will be covered in the next lecture.
