824. Goat Latin 山羊拉丁文

作者: 负雪明烛 id: fuxuemingzhu 个人博客: http://fuxuemingzhu.cn/




A sentence S is given, composed 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 S to Goat Latin.

Example 1:

Input: "I speak Goat Latin"
Output: "Imaa peaksmaaa oatGmaaaa atinLmaaaaa"

Example 2:

Input: "The quick brown fox jumped over the lazy dog"
Output: "heTmaa uickqmaaa rownbmaaaa oxfmaaaaa umpedjmaaaaaa overmaaaaaaa hetmaaaaaaaa azylmaaaaaaaaa ogdmaaaaaaaaaa"


  1. S contains only uppercase, lowercase and spaces. Exactly one space between each word.
  2. 1 <= S.length <= 150.


要把英语翻译成Goat Latin语。翻译规则如下:


  1. 如果单词以元音字母开头,后面接上"ma"
  2. 如果不以元音开头,把首字母移到最后,然后接上"ma"
  3. 每个单词后面接上在句子中出现的第几位置个"a"




class Solution:
    def toGoatLatin(self, S):
        :type S: str
        :rtype: str
        vowels = ['a', 'e', 'i', 'o', 'u', 'A', 'E', 'I', 'O', 'U']
        words = S.split(' ')
        new_words = []
        for i, word in enumerate(words):
            if word[0] in vowels:
                word += 'ma'
                word = word[1:] + word[0] + 'ma'
            word += 'a' * (i + 1)
        return ' '.join(new_words)
