Question $4.[$Points $7]$ Write a program in C$++$ for two threads to share a single resource $($e$.$g$.,$ a

license$).$ Use Peterson$$s solution to implement it$.$ Each thread independently requests for

the resource, but only one thread at a time can get it$.$ Once a thread gets the resource, it

keeps it for a random time, and releases it$.$ Then, if another thread is waiting on it$,$ it will

flag$[$i$]=$ true;

turn $=$ i;

while $($flag$[$j$]$ && turn $==$ j$)$;

lock $=$ TRUE;

flag$[$i$]=$ FALSE;

get it$.$ Here, the variables turn, flag$1$ and flag$2$ are shared variables. Variable turn is set by

either thread. Variable flag$1$ is set by thread $1$ and flag$2$ by thread$2.$ Let each thread

request and release the resource $3$ times, each time holding it for a random time and

releasing it$.$ Write the program in any language of your choice provided it allows you to

create threads. Output should look something like this.
