Suppose you have the letters P, Q, R, S with frequencies 0.4, 0.15, 0.35, and 0.1. Construct the Huffman tree for these letters and determine the encoding for each letter.
💡 Hint: Start merging the lowest frequencies first.
Explain the steps you would take to implement the heap in the Huffman coding process and why each step is necessary for efficiency.
