I have passed over my no-brainer moment:

[code]
fixed_value = ""
idx = 0
while (idx < wrong_value.size) do
	fixed_value << wrong_value[idx]
	if ( wrong_value[idx] == 39 )
		if ( (wrong_value[idx + 1] != 39) )
			if ( idx > 0 && wrong_value[idx - 1] != 39 )
				fixed_value << '\''
			end
		end
         end
         idx += 1
end
[/code]

but now i've reached the no-ruby point. Can you teach me what would be the ruby way?

Note: the double quotes are not considered in this problem; in fact i am removing them right from 
the beginning
