# 单词替换

<p>在英语中，我们有一个叫做&nbsp;<code>词根</code>(root)的概念，它可以跟着其他一些词组成另一个较长的单词&mdash;&mdash;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，给定一个由许多词根组成的词典和一个句子。你需要将句子中的所有<code>继承词</code>用<code>词根</code>替换掉。如果<code>继承词</code>有许多可以形成它的<code>词根</code>，则用最短的词根替换它。</p>

<p>你需要输出替换之后的句子。</p>
