Some examples from this set of practice questions
1.
What is a traversal algorithm in graph theory?
Answer: A traversal algorithm is a method to visit all nodes in a graph. Two common traversal algorithms are Depth-First Search (DFS) and Breadth-First Search (BFS).
2.
What is Dijkstra\'s shortest path algorithm?
Answer: Dijkstra\'s shortest path algorithm is a greedy algorithm used to find the shortest path between two nodes in a weighted graph. It works by maintaining a priority queue of the nodes with their tentative distances from the source node.
3.
What is a minimum spanning tree in a graph?
Answer: A minimum spanning tree is a tree that connects all nodes in a graph with minimum possible total edge weight. Two popular algorithms to find the minimum spanning tree are Prim\'s algorithm and Kruskal\'s algorithm.
4.
How are graphs represented in data structures?
Answer: Graphs can be represented in various data structures, such as adjacency matrix, adjacency list, and edge list.
5.
What are the different types of graphs?
Answer: The main types of graphs are directed graphs (digraphs), undirected graphs, weighted graphs, and unweighted graphs.
