I answered the following question:
4th Point Of A Rectangle - Co-Ordinate Geometry
I then learned it was part of an active contest:
https://www.codechef.com/JULY20B/problems/PTMSSNG
I voted to close the question on the grounds that it should be locked until the contest was over. It picked up some additional close votes, but it has not been locked despite receiving hundreds of additional views. What reason should I give to ensure that an active contest question is locked?
I tried to delete my answer. However, it had been accepted before I learned it was drawn from an active contest. Since it was accepted, I could not delete my answer.
