Introduction

In this blog post, we will explore how to solve the LeetCode problem "824" using AI. LeetCode is a popular platform for preparing for coding interviews, and with the help of AI tools like Chatmagic, we can generate solutions quickly and efficiently - helping you pass the interviews and get the job offer without having to study for months.

Problem Statement

You are given a string sentence that consist of words separated by spaces. Each word consists of lowercase and uppercase letters only. We would like to convert the sentence to "Goat Latin" (a made-up language similar to Pig Latin.) The rules of Goat Latin are as follows: If a word begins with a vowel ('a', 'e', 'i', 'o', or 'u'), append "ma" to the end of the word. For example, the word "apple" becomes "applema". If a word begins with a consonant (i.e., not a vowel), remove the first letter and append it to the end, then add "ma". For example, the word "goat" becomes "oatgma". Add one letter 'a' to the end of each word per its word index in the sentence, starting with 1. For example, the first word gets "a" added to the end, the second word gets "aa" added to the end, and so on. Return the final sentence representing the conversion from sentence to Goat Latin. Example 1: Input: sentence = "I speak Goat Latin" Output: "Imaa peaksmaaa oatGmaaaa atinLmaaaaa" Example 2: Input: sentence = "The quick brown fox jumped over the lazy dog" Output: "heTmaa uickqmaaa rownbmaaaa oxfmaaaaa umpedjmaaaaaa overmaaaaaaa hetmaaaaaaaa azylmaaaaaaaaa ogdmaaaaaaaaaa" Constraints: 1 <= sentence.length <= 150 sentence consists of English letters and spaces. sentence has no leading or trailing spaces. All the words in sentence are separated by a single space.

Explanation

• Split the sentence: Split the input sentence into individual words based on spaces.
  • Process each word: Iterate through the words, applying the Goat Latin transformation rules (vowel/consonant handling, "ma" addition, "a" repetition based on index).
  • Reconstruct the sentence: Join the transformed words back into a single string, separated by spaces.

• Runtime Complexity: O(n), where n is the length of the sentence. Storage Complexity: O(n), where n is the length of the sentence, due to the storage of the split words and the transformed words.

Code

    def toGoatLatin(sentence: str) -> str:
    """
    Converts a sentence to Goat Latin according to the specified rules.
    """
    words = sentence.split()
    vowels = "aeiouAEIOU"
    result = []

    for i, word in enumerate(words):
        if word[0] in vowels:
            transformed_word = word + "ma"
        else:
            transformed_word = word[1:] + word[0] + "ma"

        transformed_word += "a" * (i + 1)
        result.append(transformed_word)

    return " ".join(result)
