<p>Given an integer array <code>nums</code>, you need to find one <b>continuous subarray</b> that if you only sort this subarray in ascending order, then the whole array will be sorted in ascending order.</p>
|
|
|
|
<p>Return <em>the shortest such subarray and output its length</em>.</p>
|
|
|
|
<p> </p>
|
|
<p><strong>Example 1:</strong></p>
|
|
|
|
<pre>
|
|
<strong>Input:</strong> nums = [2,6,4,8,10,9,15]
|
|
<strong>Output:</strong> 5
|
|
<strong>Explanation:</strong> You need to sort [6, 4, 8, 10, 9] in ascending order to make the whole array sorted in ascending order.
|
|
</pre>
|
|
|
|
<p><strong>Example 2:</strong></p>
|
|
|
|
<pre>
|
|
<strong>Input:</strong> nums = [1,2,3,4]
|
|
<strong>Output:</strong> 0
|
|
</pre>
|
|
|
|
<p><strong>Example 3:</strong></p>
|
|
|
|
<pre>
|
|
<strong>Input:</strong> nums = [1]
|
|
<strong>Output:</strong> 0
|
|
</pre>
|
|
|
|
<p> </p>
|
|
<p><strong>Constraints:</strong></p>
|
|
|
|
<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>
|
|
|
|
<p> </p>
