CCS QUIZ BEE - Data Structures & Algorithms Quiz

What is the purpose of a data structure?

• To increase memory usage

• To confuse programmers

• To slow down data processing

• To organize data efficiently

What are the characteristics of a data structure?

• Correctness, Time Complexity, Space Complexity

• Memory Usage, Time Complexity, Accuracy

• Speed, Accuracy, Complexity

• Efficiency, Simplicity, Flexibility

What is the time complexity of data structure operations?

• Should be as small as possible

• Should be as large as possible

• Does not matter

• Irrelevant

Why do applications face problems with data search?

• Because of limited memory

• Due to lack of data

• Because processors are too fast

• As data grows, search becomes slower

What is the advantage of using arrays for data storage?

• O(1) random access lookup time

• O(n) random access lookup time

• O(n^2) random access lookup time

• O(log n) random access lookup time

What is a linked list?

• A linear array with N elements

• An array with a defined size

• A collection of elements with different data types

• A data structure that consists of nodes connected together via links

What are the three types of linked lists?

• Singly Linked List, Doubly Linked List, Circular Linked List

• Linear Linked List, Binary Linked List, Circular Linked List

• Single Linked List, Double Linked List, Circular Linked List

• Sequential Linked List, Double Linked List, Circular Linked List

What is the basic operation in linked lists?

• Sorting, Filtering, Grouping, Aggregating

• Insertion, Deletion, Searching, Display, Deleting an element at a given key

• Addition, Subtraction, Multiplication, Division

• Reading, Writing, Arithmetic, Logic

How is a new node added at the beginning of a linked list?

• Remove the first node and update the head pointer

• Remove the last node and update the head pointer

• Point the new node to the last node and update the head pointer

• Point the new node to the old first node and update the head pointer

What is the process for deleting an element at the end of a linked list?

• Iterate until you find the middle element and assign NULL to its next pointer

• Iterate until you find the last element and assign NULL to its next pointer

• Iterate until you find the first element and assign NULL to its next pointer

• Iterate until you find the second last element and assign NULL to its next pointer
