Solution: Sort Array by Increasing Frequency

Explore how to sort an array based on frequency and value order by tracking element counts using frequency maps. Understand applying composite sorting keys to reorder arrays efficiently, combining frequency ascending and value descending criteria.

We'll cover the following...

Statement

Given an array of integers nums, sort the array in increasing order based on the frequency of each value. If multiple values share the same frequency, sort those values in decreasing order.

Return the sorted array.

Constraints:

  • 1≤1 \leq nums.length ≤100\leq 100

  • −100≤-100 \leq ...
