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.
If I'm not mistaken u can't do that but u can go in your settings if u have an iPhone and add that email with your main one.

The statement 'a data mart is the operational database for the company' is true.
We can define a data mart as a subject-oriented database that focuses on a particular area in an organization.
It is through data mart that the employees of a company can access data faster. Data mart, functioning as the operational database, helps employees as they do not have to manually add all the data again. Also, any piece of data needed by an employee can easily be accessed through the data mart of the company.
One of the advantages of using data mart is that it eradicates human-made errors which can arise if data is added manually by an employee.
