-/**
- * 908. Smallest Range I
- *
- * Given an array A of integers, for each integer A[i] we may choose any x with -K <= x <= K, and add x to A[i].
- *
- * After this process, we have some array B.
- *
- * Return the smallest possible difference between the maximum value of B and the minimum value of B.
- *
- *
- *
- * Example 1:
- *
- * Input: A = [1], K = 0
- * Output: 0
- * Explanation: B = [1]
- * Example 2:
- *
- * Input: A = [0,10], K = 2
- * Output: 6
- * Explanation: B = [2,8]
- * Example 3:
- *
- * Input: A = [1,3,6], K = 3
- * Output: 0
- * Explanation: B = [3,3,3] or B = [4,4,4]
- *
- *
- * Note:
- *
- * 1 <= A.length <= 10000
- * 0 <= A[i] <= 10000
- * 0 <= K <= 10000
