篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了908. Smallest Range I - LeetCode相关的知识,希望对你有一定的参考价值。

Description:

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. 1 <= A.length <= 10000
  2. 0 <= A[i] <= 10000
  3. 0 <= K <= 10000

class Solution 
    public int smallestRangeI(int[] A, int K) 
        
        if(A==null||A.length==1)
            
            return 0;
        
        
        
        Arrays.sort(A);
        
  
        int second = A[0];
        
        int first = A[A.length -1];
        
        if((first - second)<=2*K)
            
            return 0 ; 
        
        
        else 
            
            return first - second - K - K ;
