Question 1.
What does Huffman's algorithm aim to achieve?
Show hintHide hint
Think about what makes an algorithm 'optimal'.
Question 2.
Why is two the base case for Huffman's algorithm?
Show hintHide hint
Consider the simplest case of assigning binary values.
3Question 3.
What is the primary strategy used in Huffman's algorithm?
- Maximize frequencies
- Merge lowest frequencies
- Assign equal frequencies
Show hintHide hint
Think about the greedy strategy!
4Question 4.
True or False: Huffman coding guarantees an optimal prefix code for given frequencies.
- True
- False
Show hintHide hint
Focus on the proof we discussed!
Question 5.
Given the frequencies of characters A=5, B=9, C=12, D=13, E=16, F=45, construct the Huffman tree and present the codes for each character.
Show hintHide hint
Start by merging A and B, then C, D, E with the previous results.
Question 6.
Explain how a heap could be integrated into Huffman’s algorithm to enhance its efficiency and the resultant benefits.
Show hintHide hint
Think about how heaps allow efficient insertions and deletions.
