Question 1. What is the optimal Huffman code for the following set of characters frequencies? a:1 b:1 c:2 d:3 e:5 f:8 g:13 h:21
Consider the following symbols with their corresponding frequencies: A:1, B:1, 0:2, D:3, E:5, F:8, G : 13, H: 21 Problem 2.a.

d, e, f, g, h, i, j, k, l}, where frequencies are given in the
table below:

We have the symbols A, B, C, D, E, F, G, H with frequencies 1, 1, 2, 4, 8, 16, 32, 64. Show the Huffman tree and Huffman code for the symbols. How much compression does a 1000 digit file use when using this Huffman code based on an 8-bit ASCII code (ie, ISO 8859-1)?
Problem (3): Huffman Coding A message contains n = 5 symbols (A, B, C, D, E) with probabilities P = (1/2, 1/4, 1/8, 1/16, 1/16), respectively. • Find a variable length Huffman coding for the 5 symbols • Find the average code length < L > for the obtained codes • Show that < L > can also be obtained by summing the probabilities of the internal nodes in the Huffman tree. • Find the coding efficiency for the obtained...

5. Eight letters {A, B, C, D, E, F,G,H} appear in a 100 letter length message with the following frequencies: 22, 6, 13, 19, 2, 9, 25, 4. (a) Use Huffman tree to design an optimal binary prefix code for the letters. (b) What is the average bit length of the message after apply codes designed in (a) to the message? [20 marks]
Write the code to implement the expression A (((B C)/D) *(E F) *G) on 3-, 2-, 1-, and 0- address machines. Do not rearrange the expression. In accordance with programming language practice, computing the expression should not change the values of its operands. When working with 0-address instructions, assume that the operation is TOS-SOS OP TOS.
