<p>给你一个包含若干 <strong>互不相同</strong>&nbsp;整数的数组&nbsp;<code>nums</code>&nbsp;，你需要执行以下操作 <strong>直到</strong><strong>数组为空</strong>&nbsp;：</p>

<ul>
	<li>如果数组中第一个元素是当前数组中的 <strong>最小值</strong>&nbsp;，则删除它。</li>
	<li>否则，将第一个元素移动到数组的 <strong>末尾</strong>&nbsp;。</li>
</ul>

<p>请你返回需要多少个操作使<em>&nbsp;</em><code>nums</code><em>&nbsp;</em>为空。</p>
