- 1.
What is Huffman coding used for?
Hint
Think about how we can represent data more efficiently.
- 2.
What do we do when we have only two nodes left in Huffman coding?
Hint
Think about binary representation.
- 3.
What is the primary purpose of Huffman coding?
- Data Encryption
- Data Compression
- Data Deletion
Hint
Think about how we minimize storage space.
- 4.
True or False: The Huffman coding algorithm guarantees the longest average encoding lengths.
- True
- False
Hint
Consider what Huffman coding aims to achieve.
- 5.
Given the following frequencies: A: 10, B: 40, C: 30, D: 20, demonstrate the step-by-step construction of a Huffman tree.
Hint
Keep track of each step visually to see how frequencies merge.
- 6.
Create your own set of character frequencies and determine the optimal encoding. Then compare with a different merging strategy.
Hint
Focus on keeping track of frequency sums as you merge.
