Suddenly, a —malicious code designed to break things—tried to block his path. Alex quickly wrote an Algorithm , a step-by-step recipe to defeat it. He wrapped his solution in Source Code , the human-readable language of the gods, before a Compiler translated it into Binary (0s and 1s) for the machines to understand.
