  1. Depth First Search (DFS) is a graph traversal algorithm that explores as far as possible along each branch before backtracking. It is commonly used for searching or traversing tree and graph data structures. DFS can be implemented either recursively or iteratively using a stack.

    Example of DFS in Python

    Here is a Python implementation of DFS using recursion:

    # Recursive DFS implementation
    def dfs(graph, node, visited=None):
    if visited is None:
    visited = set() # Initialize the visited set
    visited.add(node) # Mark the current node as visited
    print(node, end=" ") # Process the node (e.g., print it)
    for neighbor in graph[node]: # Explore all neighbors
    if neighbor not in visited:
    dfs(graph, neighbor, visited)

    # Example graph represented as an adjacency list
    graph = {
    'A': ['B', 'C'],
    'B': ['D', 'E'],
    'C': ['F'],
    'D': [],
    'E': ['F'],
    'F': []
    }

    # Perform DFS starting from node 'A'
    dfs(graph, 'A')
    Gekopieerd.

    Output:

    A B D E F C
    Gekopieerd.

    This output represents the order in which nodes are visited during the DFS traversal.
