Peterson's solution
Peterson's solution is a method used in computer science to ensure two processes access a shared resource, like a file or memory, one at a time without conflict or error. It uses two flags and a turn variable: each process indicates when it wants to access the resource (sets its flag), and the turn variable determines who gets priority. This coordination prevents both processes from entering the critical section simultaneously, ensuring safe and orderly access. The solution guarantees mutual exclusion, avoiding conflicts, deadlock, and starvation when processes follow the protocol correctly.
