Solution: Bus Routes
Explore solving the bus routes problem by building an adjacency list and applying breadth-first search (BFS) to find the shortest path from a source to a destination station. Understand how to implement BFS to track visited buses and efficiently determine the minimum number of bus transfers required, with attention to time and space complexity.
