• C++ compiler (e.g., g++)

• JSON library (https://github.com/nlohmann/json), suggest installing by apt

  sudo apt install nlohmann-json3-dev

• Base64 library (https://github.com/ReneNyffenegger/cpp-base64), .h and .cpp are included

Building the program

• Clone / download the source code from repository

• Change directory to directory containing source code cd <path>

• Compile the program using C++ compiler to generate executable file named "solution"

  g++ -std=c++11 solution.cpp base64.cpp -o solution

Running the program

• Checking exists of required input file
  • data/data.json: input JSON file
  • output-schema/schema.json: output JSON schema
• Running this command to execute the program ./solution
• Result is in output.json in the same directory
