LeetCode 1509. Minimum Difference Between Largest and Smallest V
You are given an integer array?nums
.
In one move, you can choose one element of?nums
?and change it to?any value.
Return?the minimum difference between the largest and smallest value of?nums
?after performing at most three moves.
?
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 = 0. 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 [4,7,20].?
In the second move, change 20 to 7. nums becomes [4,7,7].?
In the third move, change 4 to 3. nums becomes [7,7,7].?
After performing 3 moves, the difference between the minimum and maximum is 7 - 7 = 0.
?這個(gè)主要是思維方式要調(diào)整好,
We have 4 plans:
kill 3 biggest elements
kill 2 biggest elements + 1 smallest elements
kill 1 biggest elements + 2 smallest elements
kill 3 smallest elements
來(lái)自Lee215的想法。我還有太長(zhǎng)的路要走啊。。。
