2 threads can work consequtively by using busy waiting; as we can see below. what if there are 3 threads, how can we write it?

While (TRUE) {

flag1 = 1;

turn = 0;

while ((turn ==0) && (flag2 == 1));

critical_region();

flag1 = 0;

noncritical_region();

}

While (TRUE) {

flag2 = 1;

turn = 1;

while ((turn ==1) && (flag1 == 1));

critical_region();

flag 2 = 0;

noncritical_region();

}

How can you solve this problem for more than two processes?
