Problem: Sort Array by Increasing Frequency

med
30 min
Understand how to sort an array based on the frequency of its values, breaking ties by sorting those values in decreasing order. This lesson helps you track data efficiently for problems involving permutations, anagrams, and game design.

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:

  • 11 \leq nums.length 100\leq 100

  • 100-100 \leq nums[i] 100\leq 100
