在一条环路上有 N 个加油站,其中第 i 个加油站有汽油 gas[i] 升. 你有一辆油箱容量无限的的汽车,从第 i 个加油站开往第 i+1 个加油站需要消耗汽油 cost[i] 升.你从其中的一个加油站出发,开始时油箱为空. 如果你可以绕环路行驶一周,则返回出发时加油站的编号,否则返回 -1. 说明: 如果题目有解,该答案即为唯一答案. 输入数组均为非空数组,且长度相同. 输入数组中的元素均为非负数. 示例 1: 输入: gas = [1,2,3,4,5] cost = [3,4,5,1,2]…

  There are N gas stations along a circular route, where the amount of gas at station i is gas[i]. You have a car with an unlimited gas tank and it costs cost[i] of gas to travel from station i to its next station (i+1). You begin the journey with an…

思路: https://leetcode.com/problems/gas-station/discuss/269604/Java-Greedy-thought-process 关键是要想清楚如果从加油站A出发到不了B,那么从A到B之间的任何一个加油站出发也到不了B. 实现: #include <bits/stdc++.h> using namespace std; class Solution { public: int canCompleteCircuit(vector<int>…

在一条环路上有 N 个加油站,其中第 i 个加油站有汽油gas[i].你有一辆油箱容量无限的的汽车,从第 i 个加油站前往第 i+1 个加油站需要消耗汽油 cost[i].你从其中一个加油站出发,开始时油箱为空.如果你可以绕环路行驶一周,则返回出发时加油站的编号,否则返回-1.注意:给定的数据可保证答案是唯一的.详见:https://leetcode.com/problems/gas-station/description/ Java实现: 能走完整个环的前提是gas的总量要大于cost的总量,…

On a horizontal number line, we have gas stations at positions stations[0], stations[1], ..., stations[N-1], where N = stations.length. Now, we add K more gas stations so that D, the maximum distance between adjacent gas stations, is minimized. Retur…
