   A program that gets config path and grades the folders by that

   ✏️ 1: Path to parent folder which contains sub-folders for grade. Each folder is a user folder.
   ✏️ 2: Path to an input file for will-be executed program
   ✏️ 3: Path to correct output file
   The program iterates through the users' folders, compiles(if exists) the c file in that folder. Then runs the compiled program with the input file and comperes the results to the correct output from the config file. If anything in the way is getting wrong, the grade will be affected as listing here:
   > > > > > ✨ NO_C_FILE : 0
   > > > > > ✨ COMPILATION_ERROR: 10
   > > > > > ✨ TIMEOUT: 20
   > > > > > ✨ WRONG: 50
   > > > > > ✨ SIMILAR: 75
   The grade will be written into an excel file, named results.csv, which will be created inside the running folder.
