But in q3 both wait and signal.are atomic even though preemption happenedin p1 it can run signal again since it has signal first so making x=1 once again and run p1 so 26:59 only p2 can starve??

[@arujjwalnegi1597]

if P1 runs first, then S = 1, then it preempts to P2, executes P2's CS and then prempts again to P1, then S = 0, due to P2's wait function. So, now its going to get stuck in the wait function of P1. Hence, P1 can also starve.

1:05:11 Sir is there any formula for this. You didn't mention it in this video.

[@soonyo3430]

Its essentially the power set, so 2^n, now just remove the duplicates.

[@dipplays649]

​@@soonyo3430 bro can u explain it

[@sachinkumxr911]

but how 10 processes can be in critical section together ?? as semaphore is mutual exclusive ???????????

[@witty_reflections6]

semaphore is mutually exclusive only when s= 1 if s is greater than 1, then we can run s processes concurrently

[@knowledgeforconfidence1853]

19:51 semahore value can be negative. what we do in that situation.

[@baizeofficial484]

bro there is a while loop in wait() function it stuck in that while loop if value of semaphore is less than 0, wait() { while(S

[@brijeshmorya9737]
