I have already written the program that can run, and I need the help of the tutor to write a more efficient header; beat the reference solution I write huffman’s compression and decompression, and the tutor aims to write the header more efficiently The specific description is in picture 1. In the compression package is the part I have written: the program uses Huffman tree for compression coding: now compress.cpp and uncompress.cpp can work normally, but a better Efficient Header Design is needed. The picture 234567 are other requirements of this C++ program. you don’t need to work on them, provided for better understanding the whole program.
