Had my coderpad round at Apple (45 mins), 3 questions in total all in c.

1. Check the Endianess of the machine.
2. Debug a kernle module (It was a dead lock and few other optimization)
3. A Medium binary search question.

Solved all of them, but messed up in explaing my thought process, assumeing this is too obvious to explain.

But, it was a good learning experience.
