Questions and Answers

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

  • It assumes the input is in Camel Case
  • It assumes the input is in Sentence Case
  • It assumes the input is in Title Case (correct)
  • It assumes the input is in Lower Case

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

  • To replace spaces, underscores and hyphens
  • To remove the spaces between the gap
  • To find the gap between the first and second word (correct)
  • To lowercase the first character of the first word

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

  • To replace spaces, underscores and hyphens
  • To lowercase all characters in the input
  • To remove special characters from the input
  • To replace tabs, underscores, and hyphens with a defined separator (correct)

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

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

<p>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</p> Signup and view all the answers

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

<p>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</p> Signup and view all the answers

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

<p>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</p> Signup and view all the answers

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

<p>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</p> Signup and view all the answers
