This will THREAD your brains



An interesting question...

Consider a function PlusPlus()

static int i;

void PlusPlus()
{
i++;
}

Now 2 threads are created...

THREAD 1
PlusPlus();
PlusPlus();
PlusPlus();

THREAD 2
PlusPlus();
PlusPlus();
PlusPlus();
PlusPlus();
PlusPlus();

Assuming that all necessary work is done to set up these threads & PlusPlus function, what will be the MAX & MIN value of "i" after the threads stop executing. Support your answers with some explanations.

ASSUMPTIONS
1. The system scheduler follows random scheduling algorithm
2. Thread 1 or Thread 2, either can be executed first (because of 1st assumpt.)
