2524. Maximum Frequency Score of a Subarray You are given an integer array nums and a positive integer k. The frequency score of an array is the sum of the distinct values in the array raised to the power of their frequencies, taking the sum modulo 109 + 7. For example, the frequency score of the array [5,4,5,7,4,4] is (43 + 52 + 71) modulo (109 + 7) = 96. Return the maximum frequency score of a subarray of size k in nums. You should maximize the value under the modulo and not the actual valu...
