In the given programs for P1 and P2, tell if it is properly synchronizing the processes. Does this solution implements Mutual exclusion and progress? If not, explain your theory with an example of preemption sequence. turn is a shared variable and initial value for turn = 0;

P1	P2
While(1){ turn = 1; if(turn == 0){ CRITICAL_SECTION } turn = 0; }	While(1){ turn = 0; if(turn == 1){ CRITICAL_SECTION } turn = 1; }
