LeetCode - Gas Station There are n gas stations along a circular route, where the amount of gas at the ith station is gas[i]. You have a car with an unlimited gas tank and it costs cost[i] of gas to travel from the ith station to its next (i + 1)th station. You begin the ...
从gas[0]开始走,遇到油不够的情况,开始station就后退一步,利用以前算的结果可以只算出第一步的油量。直到最后,算出circle的连接点是否满足。 publicclassSolution {publicintcanCompleteCircuit(int[] gas,int[] cost) {intn =gas.length;intstart = 0, end = 0, have = 0, cur = 0;for(inti=0; i...
Gas Station -- LeetCode 原题链接:http://oj.leetcode.com/problems/gas-station/ 这是一道具体问题的题目,brute force的方法比较容易想到,就是从每一个站开始,一直走一圈,累加过程中的净余的油量,看它是不是有出现负的,如果有则失败,从下一个站开始重新再走一圈;如果没有负的出现,则这个站可以作为...

https://leetcode.com/problems/gas-station/题目: gas[i].cost[i] Return the starting gas station's index if you can travel around the circuit once, otherwise return -1. Note: The solution is guaranteed to be unique. 思路: 看了tag发现是贪心,想起老师上课说贪心实现起来是最简单的,最难的是...
https://leetcode.com/problems/jump-game/ 思路1:贪心 O(n) 思路就是贪心。子问题就是判断车在第i个position的时候是否可以到达i+1个position,条件就是当前第i个position所加的油gas[i] + diff(就是到达第i个position时剩下来的油,可以看做前面几站提供的补给) 大于等于cost[i]。

Given two integer arrays gas and cost, returnthe starting gas station's index if you can travel around the circuit once in the clockwise direction, otherwise return-1. If there exists a solution, it isguaranteedto beunique Example 1:
Return the starting gas station's index if you can travel around the circuit once in the clockwise direction, otherwise return -1. Note: If there exists a solution, it is guaranteed to be unique. Both input arrays are non-empty and have the same length. Each element in the input arrays...
