Solution: Minimum Number of Refueling Stops

Explore how to solve the minimum number of refueling stops problem using a greedy algorithm. Understand the implementation of a max-heap to select fuel stations efficiently, ensuring the car reaches its target with minimal stops. This lesson covers step-by-step logic, code structure, and complexity analysis for practical optimization.

We'll cover the following...

Statement

You need to find the minimum number of refueling stops that a car needs to make to cover a distance, target. For simplicity, assume that the car has to travel from west to east in a straight line. There are various fuel stations on the way that are represented as a 2-D array of stations, i.e., stations[i] =[di,fi]= [d_i, f_i] ...
