Question 1.
What happens when you merge two letters in Huffman coding?
Show hintHide hint
Think about how you combine two values.
Question 2.
Why is it important to use lower frequency letters in Huffman coding?
Show hintHide hint
Consider the need for compression.
3Question 3.
What is the first step in constructing a Huffman tree?
- Combine the highest frequencies
- Merge two lowest frequencies
- Assign codes to letters
Show hintHide hint
Think about how frequencies are organized.
4Question 4.
True or False: Huffman coding guarantees the shortest possible encoding for any set of frequencies.
- True
- False
Show hintHide hint
Consider how merging impacts encoding.
Question 5.
You are given frequencies of 0.12, 0.20, 0.23, 0.15, and 0.30. Construct the Huffman tree and provide the process.
Show hintHide hint
Combine the smallest pairs first, progressing iteratively.
Question 6.
