I submitted only one problem in the last June Challenge which was correct, but suddenly today i saw … my rating has decreased…whts the reason behind this?
rating ~ rank
the lower you rank, the more your rating will decrease.
the higher you rank, the more will it increase.
It’s all about what rank you acquire in a contest.
Rating not only depends on solving the problem but also depends on how fast you have solved it. If you participated in a contest and failed to solve any problem you will lose points.
