题目:
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
思路
思路很简单,就是先找到数组中的最大值与最小值,然后最小值加K,最大值减k,如果现在最大值还比最小值大,那最小差就是它俩差。如果最小值等于或者大于最大值,那他们最小差就是0.
下面是代码:
java
class Solution {
public int smallestRangeI(int[] A, int K) {
int min=A[0];
int max=A[0];
for(int i=0;i<A.length;++i)
{
if(A[i]>=max)
max=A[i];
if(A[i]<=min)
min=A[i];
}
min=min+K;
max=max-K;
if(max>min)
return max-min;
else
return 0;
}
}
python
class Solution:
def smallestRangeI(self, A: List[int], K: int) -> int:
return max(0,max(A)-min(A)-2*K)

本文介绍了一种算法,用于计算给定整数数组在每个元素上添加特定范围内的任意值后,所得数组的最大值与最小值之间的最小可能差值。通过实例展示了如何使用此算法,并提供了Java和Python代码实现。
