+<p>You own a <strong>Goal Parser</strong> that can interpret a string <code>command</code>. The <code>command</code> consists of an alphabet of <code>&quot;G&quot;</code>, <code>&quot;()&quot;</code> and/or <code>&quot;(al)&quot;</code> in some order. The Goal Parser will interpret <code>&quot;G&quot;</code> as the string <code>&quot;G&quot;</code>, <code>&quot;()&quot;</code> as the string <code>&quot;o&quot;</code>, and <code>&quot;(al)&quot;</code> as the string <code>&quot;al&quot;</code>. The interpreted strings are then concatenated in the original order.</p>
+
+<p>Given the string <code>command</code>, return <em>the <strong>Goal Parser</strong>&#39;s interpretation of </em><code>command</code>.</p>
+
+<p>&nbsp;</p>
+<p><strong>Example 1:</strong></p>
+
+<pre>
+<strong>Input:</strong> command = &quot;G()(al)&quot;
+<strong>Output:</strong> &quot;Goal&quot;
+<strong>Explanation:</strong>&nbsp;The Goal Parser interprets the command as follows:
+G -&gt; G
+() -&gt; o
+(al) -&gt; al
+The final concatenated result is &quot;Goal&quot;.
+</pre>
+
+<p><strong>Example 2:</strong></p>
