LeetCode ProblemApply Operations on Array to Maximize Sum of Squares
You are given a 0-indexed integer array nums and a positive integer k. You can do the following operation on the array any number of times: You have to choose k elements from the final array and calculate the sum of their squares. Return the maximum sum of squares you can achieve. Since the answer can be very large, return it modulo 109 + 7.
