Today I participated in [contest:1852]. My experience was terrible (I wasn't able to solve [problem:1852A] during the contest, hope it tells you a lot), but it's still recorded, so hopefully it'll be useful for somebody. As usual, during the first half I participate while explaining aloud what and how I do, during the second part I explain more slowly the solutions of Div.1 problems A–D.↵
