As an AI language model, I do not have access to files such as PDFs. However, I can provide a brief introduction to BFS and DFS algorithms.
BFS (Breadth-First Search) and DFS (Depth-First Search) are two commonly used algorithms in graph theory. They are used to traverse or search a graph, which is a collection of nodes and edges.
BFS algorithm starts at the root node and explores all the nodes at the current depth before moving on to the next depth. It uses a queue data structure to keep track of the visited nodes.
DFS algorithm starts at the root node and explores as far as possible along each branch before backtracking. It uses a stack data structure to keep track of the visited nodes.
Both algorithms have their advantages and disadvantages depending on the specific problem and graph structure. BFS is often used to find the shortest path between two nodes, while DFS is often used to find connected components or cycles in a graph.
