Suppose we want to compress a text consisting of 6 characters, a, b, c, d, e, fusingthe Huffman Algorithm. Give an example for which the algorithm produces at least onecodeword of length 5. In other words, you are being asked to give a set of the characterfrequencies that results in the deepest tree.
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.

Explanation:
When it comes to the field of computer science and information theory, the Huffman code is a specific type of optimal prefix code that is mostly utilized for the compression of lossless data. The process and procedures of finding or using such a code proceeds by means of Huffman coding, which is an algorithm that was developed by David A.
