topKFrequent

Given an array of strings <code>words</code> and an integer <code>k</code>, return the <code>k</code> most frequent strings.

Return the answer sorted by the frequency from highest to lowest. Sort the words with the same frequency by their lexicographical order.

&nbsp;
Example 1:

<pre>
Input: words = [&quot;i&quot;,&quot;love&quot;,&quot;leetcode&quot;,&quot;i&quot;,&quot;love&quot;,&quot;coding&quot;], k = 2
Output: [&quot;i&quot;,&quot;love&quot;]
Explanation: &quot;i&quot; and &quot;love&quot; are the two most frequent words.
Note that &quot;i&quot; comes before &quot;love&quot; due to a lower alphabetical order.
</pre>

Example 2:

<pre>
Input: words = [&quot;the&quot;,&quot;day&quot;,&quot;is&quot;,&quot;sunny&quot;,&quot;the&quot;,&quot;the&quot;,&quot;the&quot;,&quot;sunny&quot;,&quot;is&quot;,&quot;is&quot;], k = 4
Output: [&quot;the&quot;,&quot;is&quot;,&quot;sunny&quot;,&quot;day&quot;]
Explanation: &quot;the&quot;, &quot;is&quot;, &quot;sunny&quot; and &quot;day&quot; are the four most frequent words, with the number of occurrence being 4, 3, 2 and 1 respectively.
</pre>

&nbsp;
Constraints:

<ul>
	<li><code>1 &lt;= words.length &lt;= 500</code></li>
	<li><code>1 &lt;= words[i].length &lt;= 10</code></li>
	<li><code>words[i]</code> consists of lowercase English letters.</li>
	<li><code>k</code> is in the range <code>[1, The number of unique words[i]]</code></li>
</ul>

&nbsp;
Follow-up: Could you solve it in <code>O(n log(k))</code> time and <code>O(n)</code> extra space?
