Magnetic Force Between Two Balls
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 i^th 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.
Example 1
Input
position = [1,2,3,4,7], m = 3Output
3Distributing the 3 balls into baskets 1, 4 and 7 makes the magnetic forces between ball pairs [3, 3, 6], so the minimum is 3 and no larger minimum can be achieved.
Example 2
Input
position = [5,4,3,2,1,1000000000], m = 2Output
999999999We can use baskets 1 and 1000000000.
Constraints
- n == position.length
- 2 <= n <= 10^5
- 1 <= position[i] <= 10^9
- All integers in position are distinct.
- 2 <= m <= position.length
