https://gateoverflow.in/102011/made-easy

All these have same question 

In this it satisfies both mutual exclusion and progress but what about bounded waiting

I dont think it is satisfied

Please can someone answer this with explanation 

my doubt is 

if P1(waits for s2) P2(waits for s3) P3(executes CS)

then after P3 exiting CS P2 enters into CS

Now if P3 again wants to enter then P3 (acquires S2 before P1 acquires)

Then bounded wait may not satisfied 

please explain will this happen or not

Answer 1

plz let me know if i m wrong...

ok thank you i missed it

https://gateoverflow.in/108500/made-easy-test-series . In this link they have clearly specified that the synchronization mechanism is "used" by the processes P1,P2,P3. The given code of synchronization mechanism is not the entire process. Any process can use this synchronization mechanism at any location to access the critical section any number of times they are in need of. In this scenario , let us assume that the process P1 can continuously use this synchronization mechanism several times in its code without letting the interested  processes P2 AND P3 to access the critical section. So there is no bounded waiting.

you are saying that there is no loop so bounded waiting is satisfied which is not true. Because the code is just a synchronization mechanism and it is not the entire process and this code can be used by a process any number of times in its actual code to access the critical section.
