Interactive Quizzes
Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
What is the purpose of Huffman coding?
- To assign fixed-length codes to all characters
- To encode letters based on their frequency for better efficiency
- To create ambiguous codes for different letters
💡 Hint: Think about how efficiency can be enhanced using frequency.
Question 2
True or False: In a prefix code, one code can be a prefix of another.
- True
- False
💡 Hint: Consider what happens during decoding.

Challenge Problems
Push your limits with challenges.
Question 1
Assume we need to encode the letters 'A', 'B', 'C', 'D', 'E' with frequencies 0.4, 0.3, 0.2, 0.1. Create the Huffman tree, and derive the encoding for each character.
💡 Hint: Start by pairing the lowest frequencies and build upwards.
Question 2
What would happen if we allow one of the codes in a Huffman tree to be the prefix of another? Discuss the implications for encoding and decoding.
💡 Hint: Think about how this overlaps during the decoding process.
