AskAI
This problem deals with finding a route between two nodes in a directed graph. An example input is given, and the expected output is "There is a route between A and D."
"Checking if an Undirected Graph is Connected"
AskAI
This problem is about checking whether an undirected graph is connected. The input is a graph represented as a dictionary, and the output is a boolean indicating whether the graph is connected.
Detecting cycles in directed graphs
AskAI
This problem deals with finding cycles in directed graphs. Given a directed graph, the goal is to design an algorithm that can determine whether or not there is a cycle present. An example input and output is provided to illustrate how the algorithm would work.
