3. Understanding Graphs
Understanding Graphs
Before delving into traversal
algorithms, let's define a graph
as a collection of nodes
connected by edges. Graphs can
be directed or undirected, and
can have weighted edges.

that explores as far as possible
along each branch before
backtracking. It is commonly
implemented using a stack
data structure.

Unlike DFS, BFS explores the
neighbor nodes before moving
on to the next level. It is
commonly implemented using a
queue data structure.

BFS IMPLEMENTATION
BFS can be implemented
using a queue to maintain the
order of nodes to be visited. It
also requires a visited set to
prevent revisiting nodes.

shortest path and web
crawling. Both algorithms have
distinct use cases.
