Below is the initial setup for a set of processes and resources.

The initial setup is safe. Suppose P$2$ wants an additional R$1,$ is it still safe?

Show your work and explain your result.

$R1,R2,R3,R1,R2,R3$

$P1,3,2,3,P1,2,1,2$

Claim matrix Allocation matrix

$R1,R2,R3,R1,R2,R3$

Resource vector Available vector

Coordinate the actions of the two threads below by inserting wait$/$signal commands

on semaphores so that the Give order$()$ happens first, then the Take order$(),$

then the Serve meal$(),$ then the Eat meal$().$ You can assume one thread each.

Customer Waiter

Give order$()$ Take order$()$

Eat meal$()$ Serve meal$()$
