Given an array of strings words, return the words that can be typed using letters of the alphabet on only one row of American keyboard like the image below.

\n\n

In the American keyboard:

\n\n\n\"\"\n

 

\n

Example 1:

\n\n
\nInput: words = ["Hello","Alaska","Dad","Peace"]\nOutput: ["Alaska","Dad"]\n
\n\n

Example 2:

\n\n
\nInput: words = ["omk"]\nOutput: []\n
\n\n

Example 3:

\n\n
\nInput: words = ["adsdf","sfd"]\nOutput: ["adsdf","sfd"]\n
\n\n

\n\n\n", "translatedTitle": "键盘行", "translatedContent": "

给你一个字符串数组 words ，只返回可以使用在 美式键盘 同一行的字母打印出来的单词。键盘如下图所示。

\n\n

美式键盘 中：

\n\n\n\n

\"American

\n\n

 

\n\n

示例 1：

\n\n
\n输入：words = [\"Hello\",\"Alaska\",\"Dad\",\"Peace\"]\n输出：[\"Alaska\",\"Dad\"]\n
\n\n

示例 2：

\n\n
\n输入：words = [\"omk\"]\n输出：[]\n
\n\n

示例 3：

\n\n
\n输入：words = [\"adsdf\",\"sfd\"]\n输出：[\"adsdf\",\"sfd\"]\n
\n\n
