# 0910. Smallest Range II

https://leetcode.com/problems/smallest-range-ii

## Description

You are given an integer array `nums` and an integer `k`.

For each index `i` where `0 <= i < nums.length`, change `nums[i]` to be either `nums[i] + k` or `nums[i] - k`.

The **score** of `nums` is the difference between the maximum and minimum elements in `nums`.

Return _the minimum **score** of_ `nums` _after changing the values at each index_.

**Example 1:**

```
**Input:** nums = [1], k = 0
**Output:** 0
**Explanation:** The score is max(nums) - min(nums) = 1 - 1 = 0.
```

**Example 2:**

```
**Input:** nums = [0,10], k = 2
**Output:** 6
**Explanation:** Change nums to be [2, 8]. The score is max(nums) - min(nums) = 8 - 2 = 6.
```

**Example 3:**

```
**Input:** nums = [1,3,6], k = 3
**Output:** 3
**Explanation:** Change nums to be [4, 6, 3]. The score is max(nums) - min(nums) = 6 - 3 = 3.
```

**Constraints:**

* `1 <= nums.length <= 104`
* `0 <= nums[i] <= 104`
* `0 <= k <= 104`
