It uses a stack to Manage the nodes to be explored. Process: • Start from the root node and push it onto the stack. • Pop a node, process it, and push all its unvisited neighbors onto the stack. • Repeat the process until the stack is empty. Example: DFS can be used in solving puzzles like mazes, where the algorithm explores One possible path to the end, and if it hits a dead end, it backtracks and tries another Path. Complexity: The time complexity of DFS is O (V+E), similar to BFS. However, DFS is more memory-efficient for deep graphs, while BFS is more suited for shallow graphs. 00:53 DEPTH FIRST SEARCH (DFS) INTRO 03:32 PROCESS 04:05 ANIMATION EXAMPLE 07:45 VISUALIZATION #DigitalEducation #DigitalEducationLatestNews #DigitalEducationShahbazAli #11thComputerScience2025 #ComputerScience2025 #FScComputerScience #1stYearComputerScience #ComputerScienceLectures #CSPakistan #CSForBeginners #FScPart1 #CSTutorials #DigitalEducation #DFS #GraphTraversal #Algorithms #DataStructures #CodingInterview #MazeSolving #DepthFirstSearch #LearnToCode #ComputerScience Computer Science 11th class Lecturer of Computer Science By Sir Shahbaz Ali For any query or private tutoring contact (0309-0334424) [email protected]
