Please show code/PseudoCode and an explantion of the scenario where all 3 process want to enter the critical section. (code from part 1 showen as well as stated in the question)

Question 2. [Points 4] Three processes P1,P2, and P3 are sharing a resource R1 in a mutually exclusive manner. Using test_and_set instruction, show code for P1, P2, and P3 that shows the entry section and exit section (similar to the code shown in Question 1). Using this code, show a scenario if all three processes want to enter their critical sections. flag [i]= true; turn =i; while (flag[j] \& \& turn == j); Critical section Remainder
