<p>给你两个整数数组 <code>nums1</code> 和 <code>nums2</code>，长度分别为 <code>n</code> 和 <code>m</code>。同时给你一个<strong>正整数</strong> <code>k</code>。</p>
|
||
|
||
<p>如果 <code>nums1[i]</code> 可以被 <code>nums2[j] * k</code> 整除，则称数对 <code>(i, j)</code> 为 <strong>优质数对</strong>（<code>0 <= i <= n - 1</code>, <code>0 <= j <= m - 1</code>）。</p>
|
||
|
||
<p>返回<strong> 优质数对 </strong>的总数。</p>
|
||
|
||
<p> </p>

<div class="example-block">
|
||
<p><strong>输入：</strong><span class="example-io">nums1 = [1,3,4], nums2 = [1,3,4], k = 1</span></p>

<p><strong>输出：</strong><span class="example-io">5</span></p>
|

<p><strong>解释：</strong></p>
|

|
||
<p>5个优质数对分别是 <code>(0, 0)</code>, <code>(1, 0)</code>, <code>(1, 1)</code>, <code>(2, 0)</code>, 和 <code>(2, 2)</code>。</p>
