Solution: Minimum Number of Refueling Stops

Explore how to determine the minimum number of refueling stops needed for a car to reach a target distance. Learn to apply a greedy approach using max-heaps to select fuel stations optimally, ensuring efficient problem-solving and understanding of time and space trade-offs.

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] ...
