Bot Requirements

• The bot should be a HTTP server listening on port 5000 (dockerized)
• It will receive a GET request with the current game state as a state query parameter
  • The query parameter will be a string of 16 numbers separated by commas
  • These 16 numbers represent block values in col-major format (0 means an empty block)
    • https://en.wikipedia.org/wiki/Row-_and_column-major_order
  • The bot should respond with a single character (0, 1, 2, or 3) representing the following actions:
    • 0 → UP
    • 1 → RIGHT
    • 2 → DOWN
    • 3 → LEFT
  • The bot should not return anything else besides the single character response
  • Enable CORS and listen on all IPs (0.0.0.0)
