Consider this problem of bounded buffer shared memory. There are two processes who share a common memory. One process is called Produce process and other one is called Consumer Process. The buffer size is $4.$

These are the sequence of steps happening. Stepwise please show the value of IN pointer, OUT pointer and processes in Buffer. Assume that initial values of IN and OUT buffer as zero.

Step$1$: Producer Produces $$ P$1$

Step $2$ Producer Produces $P_2$

Step$3$ Producer Produces $P_3$

Step$4$ Consumer consumes P$1$

Step$5-$ Consumer Consumes, P$2$

Step$6-$ Producer Produces P$4$

Step$7-$ Producer Produces p$5$

Step$7-$ Consumer consumes P$4$
