    Respected Sanchit Sir,
    very warm Greetings. Sir your efforts are highly appreciable. You're doing absolutely great.
    with due respect i want to bring this to your knowledge that unknowingly meanwhile clearing concept of which process to entertain first you considered burst time of P4 as 4 instead of 2.
    anyway this is just an exception and I can't deny that only you'd made me understand this & and many many more concepts.
    my heartfelt gratitude towards you with much much love and respect.
    Thank You Sanchit Sir:)

      @Himanshu Tyagi CT is completion time that mean time at which our process gets complete its execution.You are right that it comes at 1 .but at time 0 our CPU was ideal,at 1 P3 comes and its burst time was 1 so it takes 1 unit ..its execution was completed on time 2 unit .so its CT is 2.Dont get confused between CT and Waiting time.
