Create a regex pattern to match all lowercase hexadecimal words
The regex pattern to match all lowercase hexadecimal words would be `^[0-9a-f]+$`. This pattern uses the start of string anchor `^` and end of string anchor `$` to match the entire string, and only allows characters in the range of 0-9 and a-f. The `+` indicates one or more of the character set, meaning that it will match strings of any length as long as all characters are valid hexadecimal characters in lowercase.
