Solution: Bus Routes

Explore how to solve the Bus Routes problem by applying graph algorithms and breadth-first search. This lesson teaches you to build an adjacency list mapping stations to bus routes and use BFS to find the minimum number of buses needed to travel between two stations. You will understand the approach to handle constraints and evaluate time and space complexities while implementing efficient graph solutions.

We'll cover the following...

Statement

You are given an array, routes, representing bus routes where routes[i] is a bus route that the ithi^{th} bus repeats forever. Every route contains one or more ...
