floor :solution links are inactive?

Hey,why solution links are not active of this past contest??

P.S-I am talking about solution links of submitted solutions :frowning:

just goto this link: http://www.codechef.com/HCKATHON/problems/FLOOR

and try to see solution of others :frowning:
Please anyone tell me the reason…

See on the contest page it says that it is an external contest i.e. the questions are not made by codechef and the rules are defined by the author if the contest. You cannot view the submissions after the contest as the author has set this rule to not show others submissions even after the contest. I hope I made it clear to you.
