Challenge Problems
Push your limits with challenges.
Question 1
Construct a Huffman Tree using the letters A (0.4), B (0.3), C (0.2), D (0.1). Then derive the corresponding binary codes.
💡 Hint: Start by identifying the two letters with the lowest frequencies.
Question 2
Given the probabilities of letters A (0.25), B (0.25), C (0.25), and D (0.25), provide an explanation of how you would use Huffman coding to minimize the length of the encoded message.
💡 Hint: Think about how you would choose to combine nodes when frequencies are equal.
