Question

When implementing Huffman Coding, a common issue arises

if the generated codes are not unique prefixes (i.e., one code is a prefix of another, leading to ambiguity during decoding). What step in the Huffman tree construction process, if implemented incorrectly, could lead to this debugging problem?

A Not sorting the initial character frequencies.

B Incorrectly combining the two lowest frequency nodes into a new parent node.

C Assigning '0' to the left child and '1' to the right child during tree traversal.

D Failing to use a priority queue to manage the nodes.

E Not handling characters with zero frequency.
