Given an array of strings <code>words</code> and a character <code>separator</code>, split each string in <code>words</code> by <code>separator</code>.

Return an array of strings containing the new strings formed after the splits, excluding empty strings.

Notes

<ul>
	<li><code>separator</code> is used to determine where the split should occur, but it is not included as part of the resulting strings.</li>
	<li>A split may result in more than two strings.</li>
	<li>The resulting strings must maintain the same order as they were initially given.</li>
</ul>

&nbsp;
Example 1:

<pre>
Input: words = [&quot;one.two.three&quot;,&quot;four.five&quot;,&quot;six&quot;], separator = &quot;.&quot;
Output: [&quot;one&quot;,&quot;two&quot;,&quot;three&quot;,&quot;four&quot;,&quot;five&quot;,&quot;six&quot;]
Explanation: In this example we split as follows:

&quot;one.two.three&quot; splits into &quot;one&quot;, &quot;two&quot;, &quot;three&quot;
&quot;four.five&quot; splits into &quot;four&quot;, &quot;five&quot;
&quot;six&quot; splits into &quot;six&quot; 

Hence, the resulting array is [&quot;one&quot;,&quot;two&quot;,&quot;three&quot;,&quot;four&quot;,&quot;five&quot;,&quot;six&quot;].</pre>

Example 2:

<pre>
Input: words = [&quot;$easy$&quot;,&quot;$problem$&quot;], separator = &quot;$&quot;
Output: [&quot;easy&quot;,&quot;problem&quot;]
Explanation: In this example we split as follows: 

&quot;$easy$&quot; splits into &quot;easy&quot; (excluding empty strings)
&quot;$problem$&quot; splits into &quot;problem&quot; (excluding empty strings)

Hence, the resulting array is [&quot;easy&quot;,&quot;problem&quot;].
</pre>

Example 3:

<pre>
Input: words = [&quot;|||&quot;], separator = &quot;|&quot;
Output: []
Explanation: In this example the resulting split of &quot;|||&quot; will contain only empty strings, so we return an empty array []. </pre>

&nbsp;
Constraints:

<ul>
	<li><code>1 &lt;= words.length &lt;= 100</code></li>
	<li><code>1 &lt;= words[i].length &lt;= 20</code></li>
	<li>characters in <code>words[i]</code> are either lowercase English letters or characters from the string <code>&quot;.,|$#@&quot;</code> (excluding the quotes)</li>
	<li><code>separator</code> is a character from the string <code>&quot;.,|$#@&quot;</code> (excluding the quotes)</li>
</ul>

Array

String

给你一个字符串数组 <code>words</code> 和一个字符 <code>separator</code> ，请你按 <code>separator</code> 拆分 <code>words</code> 中的每个字符串。

返回一个由拆分后的新字符串组成的字符串数组，不包括空字符串 。

注意

<ul>
	<li><code>separator</code> 用于决定拆分发生的位置，但它不包含在结果字符串中。</li>
	<li>拆分可能形成两个以上的字符串。</li>
	<li>结果字符串必须保持初始相同的先后顺序。</li>
</ul>

示例 1：

<pre>
输入：words = ["one.two.three","four.five","six"], separator = "."
输出：["one","two","three","four","five","six"]
解释：在本示例中，我们进行下述拆分：

"one.two.three" 拆分为 "one", "two", "three"
"four.five" 拆分为 "four", "five"
"six" 拆分为 "six" 

因此，结果数组为 ["one","two","three","four","five","six"] 。</pre>

示例 2：

<pre>
输入：words = ["$easy$","$problem$"], separator = "$"
输出：["easy","problem"]
解释：在本示例中，我们进行下述拆分：

"$easy$" 拆分为 "easy"（不包括空字符串）
"$problem$" 拆分为 "problem"（不包括空字符串）

因此，结果数组为 ["easy","problem"] 。
</pre>

示例 3：

<pre>
输入：words = ["|||"], separator = "|"
输出：[]
解释：在本示例中，"|||" 的拆分结果将只包含一些空字符串，所以我们返回一个空数组 [] 。 </pre>

&nbsp;

提示：

<ul>
	<li><code>1 &lt;= words.length &lt;= 100</code></li>
	<li><code>1 &lt;= words[i].length &lt;= 20</code></li>
	<li><code>words[i]</code> 中的字符要么是小写英文字母，要么就是字符串 <code>".,|$#@"</code> 中的字符（不包括引号）</li>
	<li><code>separator</code> 是字符串 <code>".,|$#@"</code> 中的某个字符（不包括引号）</li>
</ul>
