In the universe Earth C-137, Rick discovered a special form of magnetic force between two balls if they are put in his new invented basket. Rick has n
empty baskets, the ith
basket is at position[i]
, Morty has m
balls and needs to distribute the balls into the baskets such that the minimum magnetic force between any two balls is maximum.
Rick stated that magnetic force between two different balls at positions x
and y
is |x - y|
.
Given the integer array position
and the integer m
. Return the required force.
\n
Example 1:
\n\n\nInput: position = [1,2,3,4,7], m = 3\nOutput: 3\nExplanation: Distributing the 3 balls into baskets 1, 4 and 7 will make the magnetic force between ball pairs [3, 3, 6]. The minimum magnetic force is 3. We cannot achieve a larger minimum magnetic force than 3.\n\n\n
Example 2:
\n\n\nInput: position = [5,4,3,2,1,1000000000], m = 2\nOutput: 999999999\nExplanation: We can use baskets 1 and 1000000000.\n\n\n
\n
Constraints:
\n\nn == position.length
2 <= n <= 105
1 <= position[i] <= 109
position
are distinct.2 <= m <= position.length
在代号为 C-137 的地球上,Rick 发现如果他将两个球放在他新发明的篮子里,它们之间会形成特殊形式的磁力。Rick 有 n
个空的篮子,第 i
个篮子的位置在 position[i]
,Morty 想把 m
个球放到这些篮子里,使得任意两球间 最小磁力 最大。
已知两个球如果分别位于 x
和 y
,那么它们之间的磁力为 |x - y|
。
给你一个整数数组 position
和一个整数 m
,请你返回最大化的最小磁力。
\n\n
示例 1:
\n\n\n\n输入:position = [1,2,3,4,7], m = 3\n输出:3\n解释:将 3 个球分别放入位于 1,4 和 7 的三个篮子,两球间的磁力分别为 [3, 3, 6]。最小磁力为 3 。我们没办法让最小磁力大于 3 。\n\n\n
示例 2:
\n\n输入:position = [5,4,3,2,1,1000000000], m = 2\n输出:999999999\n解释:我们使用位于 1 和 1000000000 的篮子时最小磁力最大。\n\n\n
\n\n
提示:
\n\nn == position.length
2 <= n <= 10^5
1 <= position[i] <= 10^9
position
中的整数 互不相同 。2 <= m <= position.length
