Implement in C (15 points)
1. dp1.c - You are to provide your solution to this assignment as a single C program
named 'dp1.c using semaphore. Explain in you code (as comments) that the dead
lock will happen or not. If there is a possible deadlock, you can simply solve the
deadlock by pick the fork in order like the first solution in our slides.
