Graph Data Structures and Algorithms Quiz

What is the primary focus of this video in the series?

• Binary trees

• Sorting algorithms

• Graph traversal, addition, and removal

• Data structure design

Why is there no single algorithm for adding an item to a graph?

• Graphs are too complex

• Graphs are similar to arrays

• Graphs can have varying node connections

• Graphs are not used in programming

Which data structure does a breadth-first search (BFS) utilize?

• Linked List

• Stack

• Queue

• Array

In BFS, what happens to nodes that are adjacent to the current node?

• They are deleted

• They are pushed onto a stack

• They are marked as visited and enqueued

• They are ignored

What is a key characteristic of depth-first search (DFS)?

• It is faster than BFS

• It uses a stack

• It finds the shortest path

• It uses a queue

How does DFS differ in its approach to node traversal compared to BFS?

• DFS uses a queue, BFS uses a stack

• DFS uses a stack, BFS uses a queue

• DFS is iterative, BFS is recursive

• DFS is slower than BFS

What flexibility does DFS offer in terms of traversal paths?

• It only follows the rightmost path

• It does not allow path flexibility

• It always follows the leftmost path

• It can follow any path, leftmost or rightmost

What is a common feature of both BFS and DFS?

• Both find the shortest path

• Both are used for graph traversal

• Both use a queue

• Both use a stack

What additional resource is mentioned for further learning about algorithms?

• A software tool

• An online course

• A book on essential algorithms

• A YouTube channel

What is the benefit of implementing algorithms using recursion as mentioned in the video?

• It simplifies the algorithm

• It makes the algorithm less efficient

• It speeds up the algorithm

• It makes the algorithm more complex
