Section 3: Top Subjective Questions in Grade 10 Computer Science Examinations
1. Explain the concept of a binary tree and its applications.
– Reference Answer: A binary tree is a hierarchical data structure where each node has at most two children. It is commonly used in searching and sorting algorithms, as well as in representing hierarchical relationships.
2. Compare and contrast depth-first search and breadth-first search algorithms.
– Reference Answer: Depth-first search explores as far as possible along each branch before backtracking, while breadth-first search explores all the neighbor nodes at the present depth before moving on to the nodes at the next depth.
3. Describe the process of balancing an AVL tree and its significance.
– Reference Answer: Balancing an AVL tree involves performing rotations to ensure that the height difference between the left and right subtrees is at most 1. This ensures efficient search, insertion, and deletion operations in the tree.
4. Explain the concept of a hash table and its advantages over other data structures.
– Reference Answer: A hash table is a data structure that maps keys to values using a hash function. It provides efficient insertion, deletion, and retrieval of data, making it ideal for applications that require fast access to information.
5. Discuss the working principle of Dijkstra\’s algorithm and its applications.
– Reference Answer: Dijkstra\’s algorithm is a greedy algorithm used to find the shortest path between two nodes in a graph. It is commonly used in routing protocols and network optimization.
These are just a few examples of the fifteen subjective questions that could be asked in Grade 10 Computer Science examinations. Each question is accompanied by a detailed reference answer, providing you with a comprehensive understanding of the topic. By studying this chapter, you will be well-prepared to tackle any advanced data structures and algorithms question that comes your way.
