Dear MikeMirzayanov

I received an email about my code 267012690 matching with 266995241. Now I know that they are very similar and such coincidences are very infrequent but they do happen. I don't have a way to prove that this is in fact a coincidence but because the 1986C - Update Queries had a simple solution, this could increase the chances, resulting in my submission matching closely with wandasd's.

To further support my claim, my performance in that contest was on par with my rating (I actually dropped a little).
