Challenge Problems
Push your limits with advanced challenges
Construct a Huffman encoding tree for the characters 'a', 'b', 'c', and 'd' with frequencies 0.15, 0.30, 0.25, and 0.30 respectively. What coding will you assign to each character?
💡 Hint: Combine the two characters with lowest frequency first.
Given a sentence, analyze it to determine character frequencies. Create an optimal Huffman code, outlining the steps taken in your process.
💡 Hint: Frequency count is key before moving to coding.
