+/**
+ * 1678. Goal Parser Interpretation
+ * https://leetcode.com/problems/goal-parser-interpretation/
+ * Difficulty: Easy
+ *
+ * You own a Goal Parser that can interpret a string command. The command consists of an alphabet
+ * of "G", "()" and/or "(al)" in some order. The Goal Parser will interpret "G" as the string
+ * "G", "()" as the string "o", and "(al)" as the string "al". The interpreted strings are then
+ * concatenated in the original order.
+ *
+ * Given the string command, return the Goal Parser's interpretation of command.
