The first known correct software solution to the critical-section problem for two
processes was developed by Dekker. The two processes, P0 and P1, share the
following variables:
boolean flag[2]; /* initially false */
int turn;
The structure of process Pi (i == 0 or 1). The other process is Pj (j == 1 or 0).
Prove that the algorithm satisfies all three requirements for the critical-section
problem.

Q2)
Write a pseudo code to solve the reader writer problem using semaphore?
I want the second question

:you areto design the controller for alight that functions both as an ordinary light and also as a motion activated light and alarm. a. if the manual switch s is on, then the light l is on. b. besides the manual switch, there is a motion detector, m1, which activatesthis light. c.if motion is detected but the light is on anyway because s is on, only then a secondoutput a, an alarm, is turned on. d. the disable switch, d, disables the motion activated light and alarmbut leaves manual control operation of the light using switch s.(i)read the problem statement and clearly identify the inputs and outputs for the circuit you are designing. (ii)create the truth table for this system; include the light, alarm, switch, disable, and the motion sensor.(iii)draw a schematic of this system.
