With only write(addr, data) and read(addr, &data) APIs at your disposal, how would you devise an algorithm to detect a shorted internal signal in a black box scenario?

Very hard Difficulty

Very-hard questions are the ultimate test of your expertise and preparation. They demand not just knowledge, but creativity and strategic thinking, often addressing unique or highly technical aspects of your field.

Circuits question

Circuits questions evaluate your understanding of electronic fundamentals. Demonstrate your ability to analyze, design, and troubleshoot electrical components, showing knowledge of circuit theory and practical implementation challenges.

Here's a Hint

Consider the fundamental properties of shorted signals and how they would affect read/write operations in different test patterns and data values.
