<p>给你两棵二叉树的根节点 <code>p</code> 和 <code>q</code> ，编写一个函数来检验这两棵树是否相同。</p>
|
||
|
||
<p>如果两个树在结构上相同，并且节点具有相同的值，则认为它们是相同的。</p>
|
||
|
||
<p> </p>
|

|
||
<p><strong>示例 1：</strong></p>
|
||
<img alt="" src="https://assets.leetcode.com/uploads/2020/12/20/ex1.jpg" style="width: 622px; height: 182px;" />
|
||
<pre>
|
||
<strong>输入：</strong>p = [1,2,3], q = [1,2,3]
|
||
<strong>输出：</strong>true
|
||
</pre>
|
||
|
||
<p><strong>示例 2：</strong></p>
|
||
<img alt="" src="https://assets.leetcode.com/uploads/2020/12/20/ex2.jpg" style="width: 382px; height: 182px;" />
|
||
<pre>
|
||
<strong>输入：</strong>p = [1,2], q = [1,null,2]
|
||
<strong>输出：</strong>false

<ul>
|
||
<li>两棵树上的节点数目都在范围 <code>[0, 100]</code> 内</li>
|
||
<li><code>-10<sup>4</sup> <= Node.val <= 10<sup>4</sup></code></li>
