Both "int turn" and "boolean flag[2]" are shared between the processes in Peterson's solution. "flag" is used to indicate if a process is interested in entering the critical section, while "turn" is used to determine which process enters the critical section first. Therefore, both variables need to be shared between the processes for the algorithm to work properly.
