<p>You are given an integer array <code>nums</code>, an integer <code>k</code>, and an integer <code>multiplier</code>.</p>

<p>You need to perform <code>k</code> operations on <code>nums</code>. In each operation:</p>

<ul>
	<li>Find the <strong>minimum</strong> value <code>x</code> in <code>nums</code>. If there are multiple occurrences of the minimum value, select the one that appears <strong>first</strong>.</li>
	<li>Replace the selected minimum value <code>x</code> with <code>x * multiplier</code>.</li>
</ul>

<p>Return an integer array denoting the <em>final state</em> of <code>nums</code> after performing all <code>k</code> operations.</p>

<p>给你一个整数数组&nbsp;<code>nums</code>&nbsp;，一个整数&nbsp;<code>k</code>&nbsp;&nbsp;和一个整数&nbsp;<code>multiplier</code>&nbsp;。</p>

<p>你需要对 <code>nums</code>&nbsp;执行 <code>k</code>&nbsp;次操作，每次操作中：</p>

<ul>
	<li>找到 <code>nums</code>&nbsp;中的 <strong>最小</strong>&nbsp;值&nbsp;<code>x</code>&nbsp;，如果存在多个最小值，选择最 <strong>前面</strong>&nbsp;的一个。</li>
	<li>将 <code>x</code>&nbsp;替换为&nbsp;<code>x * multiplier</code>&nbsp;。</li>
</ul>

<p>请你返回执行完 <code>k</code>&nbsp;次乘运算之后，最终的 <code>nums</code>&nbsp;数组。</p>
