<p>给你一个字符串数组 <code>words</code> ，只返回可以使用在 <strong>美式键盘</strong> 同一行的字母打印出来的单词。键盘如下图所示。</p>
|
||
|
||
<p><strong>请注意</strong>，字符串 <strong>不区分大小写</strong>，相同字母的大小写形式都被视为在同一行<strong>。</strong></p>
|
||
|
||
<p><strong>美式键盘</strong> 中：</p>
|
||
|
||
<ul>
|
||
<li>第一行由字符 <code>"qwertyuiop"</code> 组成。</li>
|
||
<li>第二行由字符 <code>"asdfghjkl"</code> 组成。</li>
|
