Write a program that implements Huffman algorithm and test it by encoding and decoding a set of files. See files in the assignment folder for the partial pseudocode that you may use to implement the program. You have to devise the complete algorithms yourself or find them elsewhere, for example, in the textbook. The assignment folder also contains input files and correspondent expected output files. Note that different input files may be used for the grading. Submit your program source code, input files, and output files into Lab6 folder.
