Breadth/Depth First Search

Great article! Looking forward to the overview of other algorithms on graphs, including Best-First Search, Dijkstra & Floyd-Warshall algorithms.

Great post for brushing up DSA basics.
I wonder if the 3rd line of Depth First Search Pseudocode should be more precisely
setlabel ( v, UV );// the vertext 'v' is unvisited?
