22.4. Implementation Considerations

Try these first

1. 1.

   What is Huffman coding used for?

   Hint

   Think about data storage.

2. 2.

   What is the purpose of a heap in Huffman coding?

   Hint

   Consider how we can speed up searching.

3. 3.

   What is the main advantage of using Huffman coding?

   • A. It reduces file size while losing data
   • B. It compresses data without loss
   • C. It is easy to implement
   • D. It uses fixed-length codes

   Hint

   Think about the type of data compression.

4. 4.

   True or False: In Huffman coding, a node's frequency is determined by merging two frequencies.

   • True
   • False

   Hint

   Consider what combining means.

5. 5.

   Given the frequencies 5, 9, 12, 13, and 16, draw the Huffman tree and explain the merging process step by step.

   Hint

   Remember to always pick the two smallest frequencies first.

6. 6.

   Discuss two specific ways in which the performance of Huffman coding can be affected by the structure of the input frequencies.

   Hint

   Consider how frequency distribution impacts the tree's shape.
