<p>给你一个整数数组&nbsp;<code>nums</code>&nbsp;和一个正整数&nbsp;<code>k</code>,请你判断是否可以把这个数组划分成一些由&nbsp;<code>k</code>&nbsp;个连续数字组成的集合。<br />
如果可以,请返回 <code>true</code>;否则,返回 <code>false</code></p>
<p>&nbsp;</p>
<p><strong>示例 1</strong></p>
<pre>
<strong>输入:</strong>nums = [1,2,3,3,4,4,5,6], k = 4
<strong>输出:</strong>true
<strong>解释:</strong>数组可以分成 [1,2,3,4] 和 [3,4,5,6]。
</pre>
<p><strong>示例 2</strong></p>
<pre>
<strong>输入:</strong>nums = [3,2,1,2,3,4,3,4,5,9,10,11], k = 3
<strong>输出:</strong>true
<strong>解释:</strong>数组可以分成 [1,2,3] , [2,3,4] , [3,4,5] 和 [9,10,11]。
</pre>
<p><strong>示例 3</strong></p>
<pre>
<strong>输入:</strong>nums = [3,3,2,2,1,1], k = 3
<strong>输出:</strong>true
</pre>
<p><strong>示例 4</strong></p>
<pre>
<strong>输入:</strong>nums = [1,2,3,4], k = 3
<strong>输出:</strong>false
<strong>解释:</strong>数组不能分成几个大小为 3 的子数组。
</pre>
<p>&nbsp;</p>
<p><strong>提示:</strong></p>
<ul>
<li><code>1 &lt;= k &lt;= nums.length &lt;= 10<sup>5</sup></code></li>
<li><code>1 &lt;= nums[i] &lt;= 10<sup>9</sup></code></li>
</ul>
<p>&nbsp;</p>
