Huffman code min heap

Web21 nov. 2024 · Huffman Coding is a technique that is used for compressing data to reduce its size without losing any of its details. It was first developed by David Huffman and was named after him. Huffman Coding is generally used to compress the data which consists of the frequently repeating characters. Huffman Coding is a famous Greedy algorithm. WebA Huffman tree is a trie: its edges are labeled by 0, 1, and its paths spell out binary words. Huffman's algorithm uses a min-heap to construct the Huffman tree. At each step, we …
