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.
Embedded Coding question
Embedded Coding questions assess your ability to program for resource-constrained devices. Show your understanding of hardware interfaces, memory management, real-time constraints, and efficient algorithm implementation for embedded systems.
