(Project) Write a program to compress a file using a Huffman code and to decompress a file generated using this code.
The program should first read through the file and determine the number of occurrences of each character in the file and the total number of characters in the file.
The weight of each character will be the frequency count for that character.
The program should then use these weights to construct the Huffman codes for the characters in the file.
It should then read the file again and encode it using these Huffman codes and generate a file containing this encoded data.
Compute the compression ratio, which is the number of bits in the compressed file divided by the total number of bits in the original file (eight times the number of characters in the file).
The program should also provide the option of decompressing a file that was encoded using this Huffman code.
