+/**
+ * 824. Goat Latin
+ * https://leetcode.com/problems/goat-latin/
+ * Difficulty: Easy
+ *
+ * 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.
