Solution: Gas Station
Explore how to apply greedy algorithms to solve the gas station problem efficiently. Learn to determine if a circular route can be completed starting from a gas station by tracking gas and cost. Understand the optimized approach with O(n) time complexity that finds the unique valid start index or returns -1 if none exists.
Statement
There are gas stations along a circular route, where the amount of gas at the station is gas[i].
We have a car with an unlimited gas tank, and it costs cost[i] of gas to travel from the station to the next ...
