9.2.3: Efficient trees for prefix codes. Consider the following tree for a prefix code. A text file contains only characters from the set
{a,b,c,d,e,f}. The frequency of each letter in the file is: a:
5%b:
5%c:
10%d:
15%e:
25%f:
40%(b) Is there a prefix tree for the set
{a,b,c,d,e,f}that would result in fewer bits per character on average for the given frequencies of the characters?
