<p>在英语中，我们有一个叫做&nbsp;<code>词根</code>(root) 的概念，可以词根<strong>后面</strong>添加其他一些词组成另一个较长的单词——我们称这个词为&nbsp;<code>继承词</code>(successor)。例如，词根<code>an</code>，跟随着单词&nbsp;<code>other</code>(其他)，可以形成新的单词&nbsp;<code>another</code>(另一个)。</p>
<p>现在，给定一个由许多<strong>词根</strong>组成的词典 <code>dictionary</code> 和一个用空格分隔单词形成的句子 <code>sentence</code>。你需要将句子中的所有<strong>继承词</strong>用<strong>词根</strong>替换掉。如果<strong>继承词</strong>有许多可以形成它的<strong>词根</strong>，则用<strong>最短</strong>的词根替换它。</p>
<p>你需要输出替换之后的句子。</p>
<p>&nbsp;</p>
<p><strong>示例 1：</strong></p>
<pre>
<strong>输入：</strong>dictionary = ["cat","bat","rat"], sentence = "the cattle was rattled by the battery"
<strong>输出：</strong>"the cat was rat by the bat"
</pre>
<p><strong>示例 2：</strong></p>
<pre>
<strong>输入：</strong>dictionary = ["a","b","c"], sentence = "aadsfasf absbs bbab cadsfafs"
<strong>输出：</strong>"a a b c"
</pre>
<p>&nbsp;</p>
<p><strong>提示：</strong></p>
<ul>
<li><code>1 &lt;= dictionary.length&nbsp;&lt;= 1000</code></li>
<li><code>1 &lt;= dictionary[i].length &lt;= 100</code></li>
<li><code>dictionary[i]</code>&nbsp;仅由小写字母组成。</li>
<li><code>1 &lt;= sentence.length &lt;= 10^6</code></li>
<li><code>sentence</code>&nbsp;仅由小写字母和空格组成。</li>
<li><code>sentence</code> 中单词的总量在范围 <code>[1, 1000]</code> 内。</li>
<li><code>sentence</code> 中每个单词的长度在范围 <code>[1, 1000]</code> 内。</li>
<li><code>sentence</code> 中单词之间由一个空格隔开。</li>
<li><code>sentence</code>&nbsp;没有前导或尾随空格。</li>
</ul>
