Create a Huffman tree for the characters: A, B, C, D, E with frequencies: A=0.5, B=0.25, C=0.15, D=0.05, and E=0.05. Explain the encoding process.
💡 Hint: Start with the smallest frequencies and merge.
Explain how combining nodes in a Huffman tree reduces average encoding lengths.
💡 Hint: Consider how many symbols are represented with fewer bits.
