A greedy algorithm makes decisions that are:
Focus on the definition of greedy algorithms.
Given frequencies A: 0.1, B: 0.4, C: 0.2, D: 0.3, create the Huffman tree and assign binary codes.
Use the smallest frequencies first and build up.
Discuss the ramifications of using a non-greedy approach in Huffman coding. What could go wrong?
Think about how the encoding quality could degrade.
