What missing code should be added to this class to ensure that calling count$\_$even$(\{1,2,3,4,5\})$ returns $2?$

class TEST

feature

$$ count$\_$even$($arr: ARRAY$[$INTEGER$])$: INTEGER

$$ local

$$ count: INTEGER

$$ i: INTEGER

$$ do

$$ count :$=0$

$$ from

$$ i :$=1$

$$ until

$$ i $>$ arr.count

$$ loop

$$ if $\_\_\_\_$ then

$$ count :$=$ count $+1$

$$ end

$$ i :$=$ i $+1$

$$ end

$$ Result :$=$ count

$$ end

end
