Question

a. Huffman coding assigns codes to characters such that
the length of the code depends on the relative frequency or weight of the
corresponding character. Thus, it is a variable-length code. If the estimated
frequencies for letters match the actual frequency found in an encoded message, then
the length of that message will typically be less than if a fixed-length code had been
used. Due to such advantages, RadiantRay Networking Sdn Bhd uses Huffman
compression technique to encode the message before transmitting over the network to
its customer.
Suppose the message contains the following strings
"a fast runner never be afraid of dark“
a. How many bits may be required for encoding the message without using
Huffman coding?
b. Create an Huffman table indicating the number of character bits,
frequencies and the code used in transmission of the message (space is also
counted as a character)
c. What is the total size of the massage to be sent?
