I think this problem focuses extensively on algorithms too much. React is just a sprinkle on top. If you know nothing about graph theory, you're pretty much doom from the start. You don't even need to know react to solve this problem. Removing react out, the context remains the same. It also requires production-like project workflow and code which takes a decent time to setup. The problem can be solved within expected two days if solution concepts are laid out. The only thing left is the implementation, and working on it full-time.
It would be better if there are some more details on what routes are, rather than displaying them as number only. I can't verify the solution.
