<p>Given a string s represents the serialization of a nested list, implement a parser to deserialize it and return <em>the deserialized</em> <code>NestedInteger</code>.</p>
|
|
|
|
<p>Each element is either an integer or a list whose elements may also be integers or other lists.</p>
|
|
|
|
<p> </p>
|
|
<p><strong class="example">Example 1:</strong></p>
|
|
|
|
<pre>
|
|
<strong>Input:</strong> s = "324"
|
|
<strong>Output:</strong> 324
|
|
<strong>Explanation:</strong> You should return a NestedInteger object which contains a single integer 324.
|
|
</pre>
|
|
|
|
<p><strong class="example">Example 2:</strong></p>
|
|
|
|
<pre>
|
|
<strong>Input:</strong> s = "[123,[456,[789]]]"
|
|
<strong>Output:</strong> [123,[456,[789]]]
|
|
<strong>Explanation:</strong> Return a NestedInteger object containing a nested list with 2 elements:
|
|
1. An integer containing value 123.
|
|
2. A nested list containing two elements:
|
|
i. An integer containing value 456.
|
|
ii. A nested list with one element:
|
|
a. An integer containing value 789
|

<p> </p>
|
|
<p><strong>Constraints:</strong></p>
|
|
|
|
<ul>
|
|
<li><code>1 <= s.length <= 5 * 10<sup>4</sup></code></li>
|
|
<li><code>s</code> consists of digits, square brackets <code>"[]"</code>, negative sign <code>'-'</code>, and commas <code>','</code>.</li>
|
|
<li><code>s</code> is the serialization of valid <code>NestedInteger</code>.</li>
|
|
<li>All the values in the input are in the range <code>[-10<sup>6</sup>, 10<sup>6</sup>]</code>.</li>
|
|
</ul>
