4 cards from this section. Quick, good the night before a test.
What is Huffman coding used for?
Think about the purpose of reducing data size.
Define what a 'node' is in the context of a tree.
Consider what makes up a structure in a tree.
What does Huffman coding aim to achieve?
Remember, it's about reducing size.
True or False: Huffman's algorithm guarantees an optimal solution.
Think about how the combinations are structured.
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.
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.
Think about how a heap organizes data for quick access and updates.
