g Suppose we want to compress a text consisting of 6 characters,a, b, c, d, e, fusingthe Huffman Algorithm. Give an example for
Papessa [141]

Answer:

e(a) = 0

e(b) = 10

e(c) = 110

e(d) = 1110

Explanation:

The Worst case will happen when f(a) > 2*f(b) ; f(b) > 2*f(c) ; f(c) > 2*f(d) ; f(d) > 2*f(e) and f(e) > 2*f(f).

Where f(x) is frequency of character x.

Lets consider the scenario when

f(a) = 0.555, f(b) = 0.25, f(c) = 0.12, f(d) = 0.05, f(e) = 0.02 and f(f) = 0.005

Please see attachment for image showing the steps of construction of Huffman tree:- see attachment

From the Huffman tree created, we can see that endcoding e() of each character are as follows:-

e(a) = 0

e(b) = 10

e(c) = 110

e(d) = 1110

e(e) = 11110

e(f) = 11111

So we can see that maximum length of encoding is 5 in this case.

Which statement will read an entire line of input into the following string object?
Solnce55 [7]

Answer:

getline(cin, address);

Explanation:

Given

String object: address

Required

Statement that reads the entire line

The list of given options shows that the programming language is c++.

Analysing each option (a) to (e):

a. cin<<address;

The above instruction will read the string object until the first blank space.

Take for instance:

The user supplied "Lagos state" as input, only "Lagos" will be saved in address using this option.

b. cin address:

This is an incorrect syntax

c. getline(cin,address);

Using the same instance as (a) above, this reads the complete line and "Lagos state" will be saved in variable address

d. cin.get(address);

address is created as a string object and the above instruction will only work for character pointers (i.e. char*)

<em>From the above analysis, option (c) is correct.</em>
