Solution: Magnetic Force Between Two Balls

Understand how to solve problems by distributing balls to maximize the minimum magnetic force between them. This lesson guides you through sorting positions and using binary search to find optimal placement, helping you develop efficient problem-solving skills for similar coding interview questions.

Statement

In the universe Earth C-137, Rick has discovered a unique type of magnetic force between two balls when placed in his newly invented baskets. He has nn baskets, each located at specific positions given by the array position[i]. Morty has m balls and needs to distribute these balls across the baskets in such a way that the minimum magnetic force between any two balls is as large as possible.

The magnetic force between two balls placed at positions xx and yy is calculated as the absolute difference xy|x−y|.

Given an integer array position and the number of balls m, return the maximum possible value of the minimum magnetic force between any two balls after they have been placed in the baskets.

Constraints:

  • 22 \leq position.length 103\leq 10^3 ...
