Problem Breakdown

Understanding the Magnetic Force Between Two Balls Problem

Let's break down this LeetCode problem and understand what makes it challenging in interview settings.

Problem Statement

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.

How Interview Coder Helps

Get real-time assistance for Magnetic Force Between Two Balls problems during coding interviews. Interview Coder provides instant solutions and explanations.

Examples

Example 1
INPUT
position = [1,2,3,4,7], m = 3
OUTPUT
3
EXPLANATION

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.

Example 2
INPUT
position = [5,4,3,2,1,1000000000], m = 2
OUTPUT
999999999
EXPLANATION

We can use baskets 1 and 1000000000.

Constraints

n == position.length
2 <= n <= 105
1 <= position[i] <= 109
All integers in position are distinct.
2 <= m <= position.length
