<p>Given an array of integers <code>nums</code> and a positive integer <code>k</code>, check whether it is possible to divide this array into sets of <code>k</code> consecutive numbers.</p>

<p>Return <code>true</code> <em>if it is possible</em>.<strong> </strong>Otherwise, return <code>false</code>.</p>

<p>&nbsp;</p>
<p><strong class="example">Example 1:</strong></p>

<pre>
<strong>Input:</strong> nums = [1,2,3,3,4,4,5,6], k = 4
<strong>Output:</strong> true
<strong>Explanation:</strong> Array can be divided into [1,2,3,4] and [3,4,5,6].
</pre>

<p><strong class="example">Example 2:</strong></p>

<pre>
<strong>Input:</strong> nums = [3,2,1,2,3,4,3,4,5,9,10,11], k = 3
<strong>Output:</strong> true
<strong>Explanation:</strong> Array can be divided into [1,2,3] , [2,3,4] , [3,4,5] and [9,10,11].
</pre>

<p><strong class="example">Example 3:</strong></p>

<pre>
<strong>Input:</strong> nums = [1,2,3,4], k = 3
<strong>Output:</strong> false
<strong>Explanation:</strong> Each array should be divided in subarrays of size 3.
</pre>

<p>&nbsp;</p>
<p><strong>Constraints:</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>
