#### Detecting a route between two nodes in a directed graph.

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

#### Problem

```Given a directed graph, design an algorithm to find out whether there is a route between two nodes.
Example input:
A -> B
B -> C
A -> C
Example output:
There is a route between A and C.```

#### Solution

This solution is in C#. Our A.I. can create solutions in multiple languages.
```using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace InterviewQuestions
{
class Graph
{
public List<Node> Nodes { get; set; }

public Graph()
{
Nodes = new List<Node>();
}

{
}

public void AddEdge(Node from, Node to)
{
}

public bool IsRoute(Node from, Node to)
{
//BFS
Queue<Node> queue = new Queue<Node>();
queue.Enqueue(from);
while (queue.Count > 0)
{
Node current = queue.Dequeue();
if (current == to)
{
return true;
}
foreach (Node edge in current.Edges)
{
queue.Enqueue( edge);
}
}
return false;
}
}

class Node
{
public List<Node> Edges { get; set; }

public Node()
{
Edges = new List<Node>();
}
}
}```
