2968. Apply Operations to Maximize Frequency Score Hard

1/**
2 * [2968] Apply Operations to Maximize Frequency Score
3 *
4 * You are given a 0-indexed integer array nums and an integer k.
5 * You can perform the following operation on the array at most k times:
6 * 
7 * 	Choose any index i from the array and increase or decrease nums[i] by 1.
8 * 
9 * The score of the final array is the frequency of the most frequent element in the array.
10 * Return the maximum score you can achieve.
11 * The frequency of an element is the number of occurences of that element in the array.
12 *  
13 * <strong class="example">Example 1:
14 * 
15 * Input: nums = [1,2,6,4], k = 3
16 * Output: 3
17 * Explanation: We can do the following operations on the array:
18 * - Choose i = 0, and increase the value of nums[0] by 1. The resulting array is [2,2,6,4].
19 * - Choose i = 3, and decrease the value of nums[3] by 1. The resulting array is [2,2,6,3].
20 * - Choose i = 3, and decrease the value of nums[3] by 1. The resulting array is [2,2,6,2].
21 * The element 2 is the most frequent in the final array so our score is 3.
22 * It can be shown that we cannot achieve a better score.
23 * 
24 * <strong class="example">Example 2:
25 * 
26 * Input: nums = [1,4,4,2,4], k = 0
27 * Output: 3
28 * Explanation: We cannot apply any operations so our score will be the frequency of the most frequent element in the original array, which is 3.
29 * 
30 *  
31 * Constraints:
32 * 
33 * 	1 <= nums.length <= 10^5
34 * 	1 <= nums[i] <= 10^9
35 * 	0 <= k <= 10^14
36 *
