1.cur_gas[i]<0,可以得到 对于当前station i :cost[i]>gas[i],station i无法作为起点。 2.假设能从station 0到station i-1,可以得到从station 0作为起始的cur_gas[i-1]一定是大于以station i-1作为起始的cur_gas[i-1], 因为前面能到达的话,会累加很多之前正的cur_gas,这样就可以证明,如果从station ...

Can you solve this real interview question? 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
Explanation: You can't start at station 0 or 1, as there is not enough gas to travel to the next station. Let's start at station 2 and fill up with 4 unit of gas. Your tank = 0 + 4 = 4 Travel to station 0. Your tank = 4 - 3 + 2 = 3 ...
