Given an array of integers <code>nums</code>, sort the array in increasing order based on the frequency of the values. If multiple values have the same frequency, sort them in decreasing order.

Return the sorted array.

&nbsp;
Example 1:

<pre>
Input: nums = [1,1,2,2,2,3]
Output: [3,1,1,2,2,2]
Explanation: &#39;3&#39; has a frequency of 1, &#39;1&#39; has a frequency of 2, and &#39;2&#39; has a frequency of 3.
</pre>

Example 2:

<pre>
Input: nums = [2,3,1,3,2]
Output: [1,3,3,2,2]
Explanation: &#39;2&#39; and &#39;3&#39; both have a frequency of 2, so they are sorted in decreasing order.
</pre>

Example 3:

<pre>
Input: nums = [-1,1,-6,4,5,-6,1,4,1]
Output: [5,-1,4,4,-6,-6,1,1,1]</pre>

&nbsp;
Constraints:

<ul>
	<li><code>1 &lt;= nums.length &lt;= 100</code></li>
	<li><code>-100 &lt;= nums[i] &lt;= 100</code></li>
</ul>
