A concurrent system consists of $3$ processes using a shared resource $R$ in a non-preemptible and mutually exclusive manner. The processes have unique priorities in the range $1 \dots 3$, $3$ being the highest priority. It is required to synchronize the processes such ... priority]:=true; else begin V(proceed [priority]); busy:=true; end V(mutex) Give the pseudo code for the procedure release_R.

Consider the operations defined as f(X, Y, Z) = X'YZ + XY' + Y'Z' and g(X′, Y, Z) = X′YZ + X′YZ′ + XY . Iam following this method, A function is said to be complete if it can implement Complementation and OR logic / Complementation and AND logic. For function f(X,Y ... ans is X as X is complement of X', hence this is functionally incomplete). How to prove OR / AND logic is possible for f(X,Y,Z)?
