910. Smallest Range II Medium

1/**
2 * [910] Smallest Range II
3 *
4 * You are given an integer array nums and an integer k.
5 * For each index i where 0 <= i < nums.length, change nums[i] to be either nums[i] + k or nums[i] - k.
6 * The score of nums is the difference between the maximum and minimum elements in nums.
7 * Return the minimum score of nums after changing the values at each index.
8 *  
9 * Example 1:
10 * 
11 * Input: nums = [1], k = 0
12 * Output: 0
13 * Explanation: The score is max(nums) - min(nums) = 1 - 1 = 0.
14 * 
15 * Example 2:
16 * 
17 * Input: nums = [0,10], k = 2
18 * Output: 6
19 * Explanation: Change nums to be [2, 8]. The score is max(nums) - min(nums) = 8 - 2 = 6.
20 * 
21 * Example 3:
22 * 
23 * Input: nums = [1,3,6], k = 3
24 * Output: 3
25 * Explanation: Change nums to be [4, 6, 3]. The score is max(nums) - min(nums) = 6 - 3 = 3.
26 * 
27 *  
28 * Constraints:
29 * 
30 * 	1 <= nums.length <= 10^4
31 * 	0 <= nums[i] <= 10^4
32 * 	0 <= k <= 10^4
33 *
