void $P(n)$

$\{$

semwait$($sn$)$

semsignal$($s$($n$-1))$

$\}$

semwait$($s$($n$-1))$

count $=$ count $+1$

semsignal$($s$($n$-2))$

$\}$

$30$ processes $P(1),$dots,$P(30)$ are concurrently executing on a system $($see the pseudocode above with $P(n)=P(30)).$ The shared variable called count is

initialised to $7,$ while the semaphores $s1,s2,$dots,$s(n-1),$ sn are all initialised to $0.$ What is the value of count when process $P(17)$ executes semsignal$($s$16)?$
