**Problem Statement:**
Given the required input arguments, write an efficient algorithm to solve the **Gas Station** problem. Implement the required logic as specified by standard definitions for this classic algorithmic challenge.
**Hint / Expected Approach:**
Total gas ≥ total cost → solution exists; track start
**Edge Cases to Consider:**
- (1) No solution (total cost > total gas)
- (2) Single station
- (3) Solution at last station
