山羊拉丁文

遍历字符串，分割找到每个单词，依照题意进行操作即可。

            j = i
            while j < n and sentence[j] != " ":
                j += 1
            cnt += 1
            if sentence[i] in VOWELS:
                words.append(sentence[i:j] + "m" + "a" * cnt)
            else:
                words.append(sentence[i+1:j] + sentence[i] + "m" + "a" * cnt)
