Huffman coding using priority queue

1. Does Huffman code use priority queue?
2. Which algorithm is best for Huffman coding?
3. What is the running time of the Huffman encoding algorithm if the priority queue is implemented using heap?

Does Huffman code use priority queue?

Huffman coding is done with the help of the following steps. Calculate the frequency of each character in the string. Sort the characters in increasing order of the frequency. These are stored in a priority queue Q .

Which algorithm is best for Huffman coding?

Explanation: Greedy algorithm is the best approach for solving the Huffman codes problem since it greedily searches for an optimal solution.

What is the running time of the Huffman encoding algorithm if the priority queue is implemented using heap?

The explanation is: If the implementation of the priority queue is done using linked lists, the running time of Huffman algorithm is O(C^2).
