Solving the Circular Gas Station Problem: How to Find the Starting Point for a Successful Route.

Problem Overview
The task involves finding a starting gas station to complete a circular route without running out of gas.
Two arrays are provided: one for gas available at each station and another for the gas cost to travel to the next station.
If a valid starting station exists, the solution is guaranteed to be unique.

Key Variables
*Current Gaining*: Tracks the gas surplus or deficit when moving from one station to the next.
*Total Gaining*: Monitors the overall gas surplus or deficit throughout the entire route.
*Candidate Index*: Represents the current station index being evaluated as a potential starting point.

Algorithm Approach
Start at the first gas station and evaluate whether it is possible to reach the next one based on current gas and required cost.
If the current gaining becomes negative, the next station index is set as the new candidate, and current gaining is reset.
Continue this process until a solution has been found, or all stations have been evaluated.

Complexity Considerations
The number of gas stations can range from 1 to 1 million.
Gas and cost values at each station range from 1 to 1,000.
The expected time complexity for the solution is linear (O(n)).

Practical Applications
This problem is commonly posed in interviews by major companies, indicating its relevance in algorithmic problem-solving.
