Capitalize the Title

You are given a string title consisting of one or more words separated by a single space, where each word consists of English letters. Capitalize the string by changing the capitalization of each word such that:

  • If the length of the word is 1 or 2 letters, change all letters to lowercase.
  • Otherwise, change the first letter to uppercase and the remaining letters to lowercase.

Return the capitalized title.

Example 1:

Input: title = "capiTalIze tHe titLe"
Output: "Capitalize The Title"
Explanation:
Since all the words have a length of at least 3, the first letter of each word is uppercase, and the remaining letters are lowercase.

Example 2:

Input: title = "First leTTeR of EACH Word"
Output: "First Letter of Each Word"
Explanation:
The word "of" has length 2, so it is all lowercase.
The remaining words have a length of at least 3, so the first letter of each remaining word is uppercase, and the remaining letters are lowercase.

Example 3:

Input: title = "i lOve leetcode"
Output: "i Love Leetcode"
Explanation:
The word "i" has length 1, so it is lowercase.
The remaining words have a length of at least 3, so the first letter of each remaining word is uppercase, and the remaining letters are lowercase.

Constraints:

  • 1 <= title.length <= 100
  • title consists of words separated by a single space without any leading or trailing spaces.
  • Each word consists of uppercase and lowercase English letters and is non-empty.

SOLUTION:

class Solution:
    def capitalizeTitle(self, title: str) -> str:
        words = title.split()
        words = [word.lower() for word in words]
        words = [(word[0].upper() + word[1:]) if len(word) > 2 else word for word in words]
        return " ".join(words)
