<p>给定两个字符串 <code><em>s</em></code> 和 <code><em>t</em></code> ，编写一个函数来判断 <code><em>t</em></code> 是否是 <code><em>s</em></code> 的字母异位词。</p>
|
|||
|
|
|
|||
|
|
<p><strong>注意：</strong>若 <code><em>s</em></code> 和 <code><em>t</em></code><em> </em>中每个字符出现的次数都相同，则称 <code><em>s</em></code> 和 <code><em>t</em></code><em> </em>互为字母异位词。</p>

<p><strong>示例 1:</strong></p>
|
|||
|
|
|
|||
|
|
<pre>
|
|||
|
|
<strong>输入:</strong> <em>s</em> = "anagram", <em>t</em> = "nagaram"
|
|||
|
|
<strong>输出:</strong> true
|
|||
|
|
</pre>
|
|||

|
|
<strong>输出: </strong>false</pre>
|
|||
|
|
|
|||
|
|
<p> </p>

<p><strong>提示:</strong></p>
|
|||
|
|
|

|
|
<ul>
|
|||
|
|
<li><code>1 <= s.length, t.length <= 5 * 10<sup>4</sup></code></li>
|
|||
|
|
<li><code>s</code> 和 <code>t</code> 仅包含小写字母</li>
|
|||
|
