1636 - Sort Array by Increasing Frequency\.
Easy
Given an array of integers `nums`, 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_.
**Example 1:**
**Input:** nums = [1,1,2,2,2,3]
**Output:** [3,1,1,2,2,2]
**Explanation:** '3' has a frequency of 1, '1' has a frequency of 2, and '2' has a frequency of 3.
**Example 2:**
**Input:** nums = [2,3,1,3,2]
**Output:** [1,3,3,2,2]
**Explanation:** '2' and '3' both have a frequency of 2, so they are sorted in decreasing order.
**Example 3:**
**Input:** nums = [-1,1,-6,4,5,-6,1,4,1]
**Output:** [5,-1,4,4,-6,-6,1,1,1]
**Constraints:**
* `1 <= nums.length <= 100`
* `-100 <= nums[i] <= 100`
