+ * Choose a star in s.
+ * Remove the closest non-star character to its left, as well as remove the star itself.
+ * Return the string after all stars have been removed.
+ *
+ * Note:
+ *
+ * The input will be generated such that the operation is always possible.
+ * It can be shown that the resulting string will always be unique.
