Ques 16. What is the purpose of the Huffman coding algorithm?
Huffman coding is a compression algorithm that creates variable-length codes for characters based on their frequencies in the input. It produces prefix codes, ensuring that no code is a prefix of another.
Ques 17. Explain the concept of the Sieve of Eratosthenes.
The Sieve of Eratosthenes is an ancient algorithm for finding all prime numbers up to a given limit. It works by iteratively marking the multiples of each prime, starting from 2.
Ques 18. What is the purpose of the Floyd's cycle-finding algorithm?
Floyd's cycle-finding algorithm, also known as the Tortoise and the Hare algorithm, is used to detect cycles in a sequence, particularly in linked lists. It involves two pointers moving at different speeds.
Ques 19. Explain the concept of the 0/1 Knapsack problem.
The 0/1 Knapsack problem is a variation of the Knapsack problem where each item can be either selected or not selected, and the goal is to maximize the total value without exceeding the knapsack's capacity.
Ques 20. How does the Bresenham's line algorithm work?
Bresenham's line algorithm is used for drawing a line between two points in a grid. It efficiently determines the pixels to be illuminated by considering the slope of the line.
