Codechef not showing participation in long challenge

I participated in long challenge for the first time on codechef. I solved two questions but in my profile it is showing that no participation in long challenge. Why it is so?

I just started coding on codechef and don’t know much about rating system. How my participation will affect my rating? Do I always have a chance that my rating will increase or it will depend on my ranks in contests?

Read about rating procedures here.

No, it will depend on rank and how others are performing. Check the link.

Wait for some time to get rating updated. probably within 1-2 hour.
