In the following solution, $L$ and len are data shared by process $P1$ and P$2.$

L:to hold some shared data by P$1$ and P$2$; It is a list in this example

len: to indicate how many elements there are in $L$

semaphore $s1=1$;

semaphore $s2=1$;

shared list $L$;

Shared int len;

Code for $p_1$

I$1$: $P(s1)$;

L$2$: :$,P(s2),,V(s1)$;$V(s2)p_{2}PV$

I need answer apecific to a $,$state whether it is correct or not
