Solution: Gas Station

Explore how to apply a greedy algorithm to determine the starting gas station index on a circular route that allows completing the full trip. Learn to optimize the solution for time and space complexity while understanding the problem constraints and approach.

Statement

There are nn gas stations along a circular route, where the amount of gas at the ithi^{th} station is gas[i].

We have a car with an unlimited gas tank, and it costs cost[i] of gas to travel from the ithi^{th} station to the next (i+1)th(i+1)^{th} ...
