<p>给你一个下标从 <strong>0</strong> 开始的 <strong>非递减</strong> 整数数组 <code>nums</code> 。</p>
|
||
|
||
<p>你可以执行以下操作任意次：</p>
|
||
|
||
<ul>
|
||
<li>选择 <strong>两个 </strong>下标 <code>i</code> 和 <code>j</code> ，满足 <code>nums[i] < nums[j]</code> 。</li>
|
||
<li>将 <code>nums</code> 中下标在 <code>i</code> 和 <code>j</code> 处的元素删除。剩余元素按照原来的顺序组成新的数组，下标也重新从 <strong>0</strong> 开始编号。</li>
|
||
</ul>
|
||
|
||
<p>请你返回一个整数，表示执行以上操作任意次后（可以执行 <strong>0</strong> 次），<code>nums</code> 数组的 <strong>最小</strong> 数组长度。</p>
