1. Description

Minimum Difference Between Largest and Smallest Value in Three Moves

2. Solution

解析:Version 1,先对数组进行排序,如果数字个数小于5个,则最小差一定为0,否则,由于至多修改三个数字,因此最小值的情况为修改前三个数字、修改后三个数字、前面修改一个后面修改两个、前面修改两个后面修改一个,枚举四种情况的值取最小即可。

class Solution:
def minDifference(self, nums: List[int]) -> int:
if len(nums) < 5:
return 0
nums.sort()
return min(nums[-1] - nums[3], nums[-4] - nums[0], nums[-2] - nums[2], nums[-3] - nums[1])
