Write a program to implement file compression (and decompression) using Huffmans algorithm. Take input from in.txt text file.

You need to 1. read file and calculate number of appearance for each symbol in the file,

2. create tree with Huffman code

3. create vector with Huffman code 4. compress the file using Huffman code using vector with Huffman code 5. decompress compressed file using tree with Huffman code
