Matlab question In the following code, please note the missing sections labeled $?1,?2$ and $?3.$

$x=1$;

array$1=$randn$(10,1)$;

for $i=1$:$1$:$10$

if array $1($i$)?20$

$x=x?3$array$(i)$;

end

end

In order for this code to take the sum of all positive numbers in array$1,$ which of the following should replace the missing sections?

$?1$ should be $0,?2$ should be $>,?3$ should be $+$

$?1$ should be $1,?2$ should be $<,?3$ should be $+$

$?1$ should be $1,?2$ should be $>,?3$ should be $*$

$?1$ should be $0,?2$ should $b<.?3$ should be $+$
