Creating an adjacency List for DFS
- by user200081
I'm having trouble creating a Depth First Search for my program. So far I have a class of edges and a class of regions. I want to store all the connected edges inside one node of my region. I can tell if something is connected by the getKey() function I have already implemented. If two edges have the same key, then they are connected. For the next region, I want to store another set of connected edges inside that region, etc etc. However, I am not fully understanding DFS and I'm having some trouble implementing it. I'm not sure when/where to call DFS again. Any help would be appreciated!
class edge
{
private:
int source, destination, length;
int key;
edge *next;
public:
getKey(){ return key; }
}
class region
{
edge *data;
edge *next;
region() { data = new edge(); next = NULL; }
};
void runDFS(int i, edge **edge, int a)
{
region *head = new region();
aa[i]->visited == true;//mark the first vertex as true
for(int v = 0; v < a; v++)
{
if(tem->edge[i].getKey() == tem->edge[v].getKey()) //if the edges of the vertex have the same root
{
if(head->data == NULL)
{
head->data = aa[i];
head->data->next == NULL;
} //create an edge
if(head->data)
{
head->data->next = aa[i];
head->data->next->next == NULL;
}//if there is already a node connected to ti
}
if(aa[v]->visited == false)
runDFS(v, edge, a); //call the DFS again
} //for loop
}
