hi Questiion about Eudyptula Challenge Task 05

[Sudip Mukherjee]

hi,
sorry i cant help you with this. the rules of the challenge says "you
really should be doing your own work" .
i can only say you that I have taken almost one month for this one . I
am currently at task 18 and i still think this one was the toughest of
all the tasks til now. but after  finishing it you will surely say
"s**** its this easy .. " .. well .. atleast i said .. :)

thanks
sudip
