WebWe refuel from 0 liters to 60 liters of gas. Then, we drive from position 10 to position 60 (expending 50 liters of fuel), and refuel from 10 liters to 50 liters of gas. We then drive to and reach the target. We made 2 refueling stops along the way, so we return 2 . Note: 1 <= target, startFuel, stations [i] [1] <= 10^9 0 <= stations.length <= 500 Web8 mei 2014 · Yes O(n) is possible. Definitely not TSP. Let x i be the amount of gas available at station i minus the amount of gas required to go to next station.. A requirement is Σ x i ≥ 0 (enough gas to complete a full circle).. Consider S i = x 1 + x 2 + ... + x i. Note that S n ≥ 0..
