What is Huffman coding used for?
Think about data storage.
What is the purpose of a heap in Huffman coding?
Consider how we can speed up searching.
What is the main advantage of using Huffman coding?
Think about the type of data compression.
True or False: In Huffman coding, a node's frequency is determined by merging two frequencies.
Consider what combining means.
Given the frequencies 5, 9, 12, 13, and 16, draw the Huffman tree and explain the merging process step by step.
Remember to always pick the two smallest frequencies first.
Discuss two specific ways in which the performance of Huffman coding can be affected by the structure of the input frequencies.
Consider how frequency distribution impacts the tree's shape.
