Challenge Problems
Push your limits with advanced challenges
Using the letters A, B, C, and D with frequencies 10, 15, 30, and 45 respectively, draw the Huffman tree and provide the bit encoding for each letter.
💡 Hint: Keep merging the two smallest frequencies until you reach one tree.
Assuming you have the letters E, F, G with frequencies 12, 5, 8, explain why merging E and F first is a suboptimal choice in an imagined scenario with a higher frequency letter.
💡 Hint: Analyze how splitting larger frequencies affects the overall encoding.
