It’s either going to be 58 or 63, is my guess before IRB. :slight_smile:

It’s pretty clear to see that this will return ??(63) without looking
further
into the structure of the code, but let’s take a closer look at the
order in
which the ternaries are executed anyway:
a = ?? ? (??) : (?? ? (?? ? ?? : ??) : (?? ? ?? : ??))
So we have:
if 63
63
else
if 63
if 63
63
else
63
end
else
if 63
63
else
63
end
end
end
Result: 63
