Leetcode 1509. Minimum Difference Between Largest and Smallest Value in Three Moves [Python]
作者:互联网
可处理三次,那么能处理的其实是“丢掉”3个最小的数字或者3个最大的数字,或者6个数字里选3个(最小,次小,最大)(最小,次大,最大),所以也就是要在这4种subarray中选出最大最小值差最小的那个。
先sort,选出上述4种newnums。计算差值,找最小。
class Solution:
def minDifference(self, nums: List[int]) -> int:
if len(nums) <= 4:return 0
nums.sort()
newnum1 = nums[:-3]
newnum2 = nums[1:-2]
newnum3 = nums[2:-1]
newnum4 = nums[3:]
arr = [ newnum1, newnum2, newnum3, newnum4]
res = float('inf')
for thenums in arr:
res = min(res, max(thenums) - min(thenums))
return res
