Re: [algogeeks] Graphs.
int count=0;
for every vertex v{
if visited[v]==0
dfs(v)
count++;
}
count is the number of components in graph or m i missing something
?

[algogeeks] graphs again
A graph is given. You need to design a data structure with minimum space complexity such that it does the follows -- Finds whether nodes u and v have a path in between them in O(1) time. -- Finds whether there is a path of length k between u and v in O(k) time. The same data structure to be used for both the purposes. -- With Regards, Jalaj Jaiswal +919026283397 B.TECH IT IIIT ALLAHABAD -- You received this message because you are subscribed to the Google Groups Algorithm Geeks group.
