+/***************************************************************************************************** 
+ *
+ * A sentence is a list of words that are separated by a single space with no leading or trailing 
+ * spaces. Each word consists of lowercase and uppercase English letters.
+ * 
+ * A sentence can be shuffled by appending the 1-indexed word position to each word then rearranging 
+ * the words in the sentence.
+ * 
+ * 	For example, the sentence "This is a sentence" can be shuffled as "sentence4 a3 is2 This1" 
+ * or "is2 sentence4 This1 a3".
+ * 
+ * Given a shuffled sentence s containing no more than 9 words, reconstruct and return the original 
+ * sentence.
+ * 
+ * Example 1:
+ * 
+ * Input: s = "is2 sentence4 This1 a3"
+ * Output: "This is a sentence"
+ * Explanation: Sort the words in s to their original positions "This1 is2 a3 sentence4", then remove 
+ * the numbers.
+ * 
+ * Example 2:
+ * 
+ * Input: s = "Myself2 Me1 I4 and3"
+ * Output: "Me Myself and I"
+ * Explanation: Sort the words in s to their original positions "Me1 Myself2 and3 I4", then remove the 
+ * numbers.
+ * 
+ * Constraints:
+ * 
+ * 	2 <= s.length <= 200
+ * 	s consists of lowercase and uppercase English letters, spaces, and digits from 1 to 9.
+ * 	The number of words in s is between 1 and 9.
+ * 	The words in s are separated by a single space.
+ * 	s contains no leading or trailing spaces.
