hi
as partially color blind person i having problems with the site,for example at problems 81 ~ 83 i could not notice the
path sum at the example at all (i having difficulties to distinguish between red & black) the only way i could read and
notice the path sum was to save the page at my computer and to change the page html code so i can read it
i'm sure that other people might had the same problem and my suggestion is if you guys can please make things like
the path sum and other stuff easier to read for people who have such problem (for example image if whole text at the
path sum was black,its was impossible to see the path)
