<p>给定一个未排序的整数数组 <code>nums</code> ，找出数字连续的最长序列（不要求序列元素在原数组中连续）的长度。</p>
|
||
|
||
<p>请你设计并实现时间复杂度为 <code>O(n)</code><em> </em>的算法解决此问题。</p>
|
||
|
||
<p> </p>
|
||
|
||
<p><strong>示例 1：</strong></p>
|
||
|
||
<pre>
|
||
<strong>输入：</strong>nums = [100,4,200,1,3,2]
|
||
<strong>输出：</strong>4
|
||
<strong>解释：</strong>最长数字连续序列是 <code>[1, 2, 3, 4]。它的长度为 4。</code></pre>
|
||
|
||
<p><strong>示例 2：</strong></p>
|
||
|
||
<pre>
|
||
<strong>输入：</strong>nums = [0,3,7,2,5,8,4,6,0,1]
|
||
<strong>输出：</strong>9
|
||
</pre>
|
||
|
||
<p> </p>
|
||
|
||
<p><strong>提示：</strong></p>
|
||
|
||
<ul>
|
||
<li><code>0 <= nums.length <= 10<sup>5</sup></code></li>
|
||
<li><code>-10<sup>9</sup> <= nums[i] <= 10<sup>9</sup></code></li>
|
||
</ul>
