Leetcode Problem 871. Minimum Number of Refueling Stops

871. Minimum Number of Refueling Stops

Leetcode Solutions

Initialize a max-heap to keep track of the fuel from gas stations we've passed.
Initialize tank to startFuel and stops to 0.
Iterate through each station, and at each step: a. If the current fuel (tank) is less than the distance to the next station, refuel from the max-heap until we can reach the next station or the heap is empty. b. Increase stops each time we refuel. c. If we can't reach the next station and the heap is empty, return -1.
After processing all stations, if the current fuel (tank) is less than the distance to the target, continue refueling from the max-heap.
Return the number of stops if the target is reached; otherwise, return -1.
