<p>有个内含单词的超大文本文件,给定任意两个单词,找出在这个文件中这两个单词的最短距离(相隔单词数)。如果寻找过程在这个文件中会重复多次,而每次寻找的单词不同,你能对此优化吗?</p>
|
||||
|
||||
<p><strong>示例:</strong></p>
|
||||
|
||||
<pre><strong>输入:</strong>words = ["I","am","a","student","from","a","university","in","a","city"], word1 = "a", word2 = "student"
|
||||
<strong>输出:</strong>1</pre>
|
||||
|
||||
<p>提示:</p>
|
||||
|
||||
<ul>
|
||||
<li><code>words.length <= 100000</code></li>
|
||||
</ul>
