<p>在两条独立的水平线上按给定的顺序写下 <code>nums1</code> 和 <code>nums2</code> 中的整数。</p>
|
||||
|
||||
<p>现在,可以绘制一些连接两个数字 <code>nums1[i]</code> 和 <code>nums2[j]</code> 的直线,这些直线需要同时满足满足:</p>
|
||||
|
||||
<ul>
|
||||
<li> <code>nums1[i] == nums2[j]</code></li>
|
||||
<li>且绘制的直线不与任何其他连线(非水平线)相交。</li>
|
||||
</ul>
|
||||
|
||||
<p>请注意,连线即使在端点也不能相交:每个数字只能属于一条连线。</p>
|
||||
|
||||
<p>以这种方法绘制线条,并返回可以绘制的最大连线数。</p>
|
||||
|
||||

<p><strong>示例 1:</strong></p>
|
||||
<img alt="" src="https://assets.leetcode.com/uploads/2019/04/26/142.png" style="width: 400px; height: 286px;" />
|
||||
<pre>
|
||||
<strong>输入:</strong>nums1 = <span id="example-input-1-1">[1,4,2]</span>, nums2 = <span id="example-input-1-2">[1,2,4]</span>
|
||||
<strong>输出:</strong><span id="example-output-1">2</span>
|
||||
<strong>解释:</strong>可以画出两条不交叉的线,如上图所示。
|
||||
但无法画出第三条不相交的直线,因为从 nums1[1]=4 到 nums2[2]=4 的直线将与从 nums1[2]=2 到 nums2[1]=2 的直线相交。
|
||||
</pre>
|
||||
|

<div>
|
||||
<p><strong>示例 2:</strong></p>
|
||||
|
||||
<pre>
|
||||
<strong>输入:</strong>nums1 = <span id="example-input-2-1">[2,5,1,2,5]</span>, nums2 = <span id="example-input-2-2">[10,5,2,1,5,2]</span>
|
||||
<strong>输出:</strong><span id="example-output-2">3</span>
|
||||
</pre>
|
||||
|
||||
<div>
|
||||
<p><strong>示例 3:</strong></p>
|
||||
|
||||
<pre>
|
||||
<strong>输入:</strong>nums1 = <span id="example-input-3-1">[1,3,7,1,7,5]</span>, nums2 = <span id="example-input-3-2">[1,9,2,5,1]</span>
|
||||
<strong>输出:</strong><span id="example-output-3">2</span></pre>
|
||||
|
||||
<p> </p>
|

</div>
|
||||
</div>

|
||||
<p><strong>提示:</strong></p>
|
||||
|
||||
<ul>
|
||||
<li><code>1 <= nums1.length, nums2.length <= 500</code></li>
|
||||
<li><code>1 <= nums1[i], nums2[j] <= 2000</code></li>
