Huffman Tree Quiz

What is the primary purpose of a Huffman Tree?

• Sorting data

• Compressing data

• Searching data

• Encrypting data

In Huffman coding, which characters are assigned the shortest codes?

• The most frequent characters

• The least frequent characters

• Characters in alphabetical order

• Random characters

Which of the following is true about a Huffman Tree?

• It is a binary search tree

• It is a full binary tree

• It is a complete binary tree

• It is a ternary tree

What is the first step in constructing a Huffman Tree?

• Sorting the characters by frequency

• Creating leaf nodes for each character

• Combining the two least frequent nodes

• Building the root node

How do you calculate the total length of a Huffman encoded string?

• Multiply the frequency of each character by its code length

• Sum the frequencies of all characters

• Multiply the sum of code lengths by the number of characters

• Add the number of bits in the tree
