Test Driven Development

So they won a programming competition by gaming the scoring system harder than a speedrunner exploiting glitches. The strategy? Solve 2 problems properly, then for the other 2, just hardcode a random answer and pray it matches enough test cases to rack up points. It's like studying for an exam by memorizing one specific answer without knowing the question.

The beautiful irony here is that the competition was literally designed to prevent this exact behavior by hiding the test cases. But when you're scored purely on passing tests rather than actual correctness, you've accidentally created an incentive structure that rewards educated guessing over problem-solving. The organizers basically turned "Test Driven Development" into "Test Driven Deception."

This is why production code has edge cases that break everything—somewhere, someone wrote a function that returns 42 because "it worked in testing."
