<p>给你一个整数数组 <code>nums</code> ，你需要找出一个 <strong>连续子数组</strong> ，如果对这个子数组进行升序排序，那么整个数组都会变为升序排序。</p>
|
|||
|
|
|
|||
|
|
<p>请你找出符合题意的 <strong>最短</strong> 子数组，并输出它的长度。</p>

<p><strong>示例 1：</strong></p>
|
|||
|
|
|
|||
|
|
<pre>
|
|||
|
|
<strong>输入：</strong>nums = [2,6,4,8,10,9,15]
|
|||
|
|
<strong>输出：</strong>5
|
|||
|
|
<strong>解释：</strong>你只需要对 [6, 4, 8, 10, 9] 进行升序排序，那么整个表都会变为升序排序。

|
|
<strong>输入：</strong>nums = [1,2,3,4]
|

|
|
<pre>
|
|||
|
|
<strong>输入：</strong>nums = [1]
|
|||
|
|
<strong>输出：</strong>0

|
|
<ul>
|
|||
|
|
<li><code>1 <= nums.length <= 10<sup>4</sup></code></li>
|
|||
|
|
<li><code>-10<sup>5</sup> <= nums[i] <= 10<sup>5</sup></code></li>
|
|||
|
|
</ul>
