Minimize Max Distance to Gas Station

Explore methods to minimize the largest distance between gas stations by adding new stations at optimal positions along a number line. Understand how to apply modified binary search to handle placement and calculate the smallest possible maximum gap.

Statement

You are given an integer array, stations, representing the positions of existing gas stations along the x-axis. You are also given an integer k, indicating the number of additional gas stations you must add. These new gas stations can be placed at any position along the x-axis, including non-integer locations.

A penalty is the maximum distance between two adjacent gas stations after placing the k new stations. Your task is to return the smallest possible value of this penalty. An answer is correct if it is within 10610^{-6} ...
