"content":"<p>You are given a string <code>s</code> that contains some bracket pairs, with each pair containing a <strong>non-empty</strong> key.</p>\n\n<ul>\n\t<li>For example, in the string <code>"(name)is(age)yearsold"</code>, there are <strong>two</strong> bracket pairs that contain the keys <code>"name"</code> and <code>"age"</code>.</li>\n</ul>\n\n<p>You know the values of a wide range of keys. This is represented by a 2D string array <code>knowledge</code> where each <code>knowledge[i] = [key<sub>i</sub>, value<sub>i</sub>]</code> indicates that key <code>key<sub>i</sub></code> has a value of <code>value<sub>i</sub></code>.</p>\n\n<p>You are tasked to evaluate <strong>all</strong> of the bracket pairs. When you evaluate a bracket pair that contains some key <code>key<sub>i</sub></code>, you will:</p>\n\n<ul>\n\t<li>Replace <code>key<sub>i</sub></code> and the bracket pair with the key's corresponding <code>value<sub>i</sub></code>.</li>\n\t<li>If you do not know the value of the key, you will replace <code>key<sub>i</sub></code> and the bracket pair with a question mark <code>"?"</code> (without the quotation marks).</li>\n</ul>\n\n<p>Each key will appear at most once in your <code>knowledge</code>.
