What does the given code snippet assume about the input (in_name)?

It assumes the input is in Title Case

What is the purpose of the 'regexp_match' function in the code?

To find the gap between the first and second word

What is the role of the 'regexp_replace' function with the pattern '[ _-]+'?

To replace tabs, underscores, and hyphens with a defined separator

What is the purpose of the 'lower' function in the final result?

To lowercase the first character of the first word

The given code snippet is designed to convert a Title Case input (in_name) into camelCase.

True

The first character of the first word in the input is always converted to lowercase in the resulting output.

True

The 'regexp_replace' function with the pattern '[a-z]{1}\s+[A-Z]{1}' removes the space between the gap in the input.

False

The 'regexp_replace' function with the pattern '[\s_-]+' replaces spaces, underscores, and hyphens by an empty space for camelCase output.

False

Match the following functions with their respective purposes in the given code snippet:

regexp_match = Identifying the gap between the first and second word in the input regexp_replace with pattern '[a-z]{1}\s+[A-Z]{1}' = Removing the space between the gap in the input regexp_replace with pattern '[\s_-]+' = Replacing spaces, underscores, and hyphens by an empty space for camelCase output lower = Lowering the first character of the first word in the input

Match the following actions with their respective descriptions in the given code snippet:

Assuming that the input (in_name) is Title Case = The input is expected to have each word capitalized The gap between the first and second word is important = There is a specific emphasis on the space between the first and second words in the input Removes the space between the gap = Eliminates the space between the first and second words in the input Lowers the first character of the first word and keeps the rest as-is = Converts the first character of the first word to lowercase while retaining the rest as-is

Match the following variables with their respective usage in the given code snippet:

g = Stores the result of identifying the gap between the first and second word in the input name2 = Stores the modified version of 'in_name' after removing spaces, underscores, and hyphens result = Stores the final output after converting 'in_name' to camelCase sep = Stores a defined separator used for replacing spaces, underscores, and hyphens

Match the following expressions with their respective functions in the given code snippet:

regexp_match(in_name, '([a-z]{1})(\s+)([A-Z]{1})') = Identifying the gap between the first and second word in 'in_name' regexp_replace(in_name, '[a-z]{1}\s+[A-Z]{1}', g || g) = Replacing spaces between words based on identified gap regexp_replace(name2, '[\s_-]+', sep, 'g') = Replacing spaces, underscores, and hyphens by a defined separator lower(substring(name2, 1, 1)) || substring(name2, 2, length(name2)) = Lowering first character of first word and retaining rest
