LeetCode 3374: First Letter Capitalization II Solution

Explanation

To solve this problem, we need to iterate through each word in the content_text column, apply the capitalization rules as mentioned in the problem description, and then construct the converted_text accordingly. We can split the text into words using spaces as delimiters and then process each word individually based on the rules provided.

• Split the content_text into words.
• For each word:
  • If the word contains a hyphen, split it into parts and capitalize each part.
  • Otherwise, capitalize the first letter and convert the rest to lowercase.
• Reconstruct the converted_text by joining the processed words.
• Return the result table with content_id, original_text, and converted_text.

Time Complexity: O(n * m) where n is the number of words and m is the average length of a word. Space Complexity: O(n) for storing the converted text.
