This technical problem deals with finding a route between two nodes in a directed graph. An example input is given, and the expected output is "true" if there is a route between the two nodes.

This technical problem deals with finding a route between two nodes in a directed graph. An example input is given, as well as the desired output.

This technical problem deals with finding a route between two nodes in a directed graph. An example input and output is given.

The problem asks for a way to determine whether there is a route between two nodes in a directed graph. One example is given, where the nodes are connected in a linear fashion. The solution should work for more general cases as well.

This problem asks for the shortest route between two nodes in a graph. The input is a list of nodes and their connections. The output should be the shortest route between the two given nodes.

This problem is about detecting cycles in undirected graphs. Given a graph, the function should return true if there is a cycle, and false otherwise.
