Consider the following code. What is the output when the code is executed $?$

def structure$($a$,$ b$)$:

temp $=[]$

for e in range$($a$,$b$)$:

if e$\%2==0$:

temp. append $("$even$")$

else:

temp. append $("$odd$")$

return temp

def restructure$($data$)$:

return set$($data$)$

data $=$ structure$(1,6)$

result $=$ restructure$($data$)$

print$($f$\text{'}$Size $-\{$len$($result$)\}\text{'})$

$\{$ "even", "odd" $\}$

$$ Size $=2$

$$ Size $=4$

$$ Size $=3$
