Sort by Popularity
Sort the values in nums so that more frequent values come first. Values with the same frequency are ordered by value, smallest first. Equal values stay grouped together.
Return the sorted array.
Example 1
Input: nums = [4, 6, 2, 6, 4, 4] Output: [4, 4, 4, 6, 6, 2]
Example 2
Input: nums = [3, 1, 2] Output: [1, 2, 3]
Constraints
- 0 <= nums.length <= 10^5
- -10^5 <= nums[i] <= 10^5
Hint 1
Count each value first.
Hint 2
Sort with a comparator on (frequency descending, value ascending).

Run checks your code on 2 sample tests. Submit runs all 7 tests, including hidden ones, and earns points. Use console.log to debug. Python's first run can take a few seconds while it starts.
