Description
Given an integer array nums, in each move you may pick any element and set it to any value. After at most three such moves, return the minimum possible difference between the largest and smallest values remaining in nums.
Example 1:
Input: nums = [5,3,2,4]
Output: 0
Explanation: We can make at most 3 moves.
In the first move, change 2 to 3. nums becomes [5,3,3,4].
In the second move, change 4 to 3. nums becomes [5,3,3,3].
In the third move, change 5 to 3. nums becomes [3,3,3,3].
After performing 3 moves, the difference between the minimum and maximum is 3 - 3 = 0.
Example 2:
Input: nums = [1,5,0,10,14]
Output: 1
Explanation: We can make at most 3 moves.
In the first move, change 5 to 0. nums becomes [1,0,0,10,14].
In the second move, change 10 to 0. nums becomes [1,0,0,0,14].
In the third move, change 14 to 1. nums becomes [1,0,0,0,1].
After performing 3 moves, the difference between the minimum and maximum is 1 - 0 = 1.
It can be shown that there is no way to make the difference 0 in 3 moves.
Example 3:
Input: nums = [3,100,20]
Output: 0
Explanation: We can make at most 3 moves.
In the first move, change 100 to 7. nums becomes [3,7,20].
In the second move, change 20 to 7. nums becomes [3,7,7].
In the third move, change 3 to 7. nums becomes [7,7,7].
After performing 3 moves, the difference between the minimum and maximum is 7 - 7 = 0.
