Answer:---------
The Huffman tree is the binary tree with minimum external path weight, i.e., the one with the minimum sum of weighted path lengths for the given set of leaves. So the goal is to build a tree with the minimum external path weight.

You will construct a Huffman tree based on the given frequencies of 26 English alphabets in upper case plus the space character. An internal tree node class in HuffmanTree with necessary information is required. • You will not randomly switch left and right children when merger two trees. Instead, you will build a right-heavy tree according to the following strategies to select the right child. (1) The tree that is taller will be the right child, i.e., the height is...
