Capitalize the Title

This problem asks us to capitalize a title according to specific rules. For words with length 1 or 2, all characters should be lower case. For words with length greater than 2, only the first character should be upper case and the remaining characters should be lower case.

We can solve this problem by iterating through all the words in the title and applying the respective transformation based on the length of each word.

class Solution:
    def capitalizeTitle(self, title: str) -> str:
        words = title.split(' ')  # split the title into words
        for i in range(len(words)):
            if len(words[i]) <= 2:  # if the word has length of 1 or 2
                words[i] = words[i].lower()  # change all letters to lowercase
            else:  # if the word has length of more than 2
                words[i] = words[i][0].upper() + words[i][1:].lower()  # capitalize the first letter and make the rest lowercase
        return ' '.join(words)  # join the words back together

This code first splits the title into words. Then it iterates over all words and checks their lengths. If the length of a word is 1 or 2, it changes all letters to lower case. If the length of a word is more than 2, it changes the first letter to upper case and the remaining letters to lower case. Finally, it joins all the transformed words back together into a single string.
