Answer the following question related to the code below

int t $=0,$ z $=0,$ g $=0,$ s $=0,$ i $=0$;

while $($i $<50)$

$\{$

scanf$("\%$d$",$ &t$)$;

s $=$ s $+$ t;

if $($t $>=0)$

$\{$

g $=$ g $+1$;

$\}$

else

$\{$

z $=$ z $+1$;

$\}$

i $=$ i $+1$;

$\}$

The value stored in variable z at the end of the execution of the loop could best be described as $\_\_\_\_\_\_\_\_\_\_.$
