C$++$ Huffman coding project.

$1.$ Determine character frequencies by quickly scanning the input string $($or file$)$ that needs to be encoded and noting the number of instances of each unique character you come across.$[10]$

$2.$ Create an encoding tree: Use an approach to create a binary tree.$[30]$

$3.$ Create an encoding map: Go through the binary tree and note each character's binary encoding in a map for easy access later. $[20]$

$4.$ Encrypt the document $(/$input string$)$: Use the step $3$ and encrypt the input string$/$file$.[15]$
