goatLatin.js

// 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.
