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`
