Grokking the Coding Interview Patterns in Python

Gas Station

Explore how to identify the gas station index that allows completing a circular route by collecting and consuming gas efficiently. Understand the problem constraints and apply greedy techniques to optimize the solution. Practice implementing the approach in code to prepare for related coding interview questions.

We'll cover the following...

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  ...
