I really failed this time, first time I fail the deadline since the 96 hours deadline for div1 hard's editorial was added . The problem was that div1 900's is not difficult, but I completely underestimated the time it took me to code it correctly (had a very dumb bug last night and I couldn't debug it and kept falling asleep). Then explaining it was impressively hard.
This was a good match. I was angry the last day because of missing it. I still think the 600 points problem wasn't suitable for medium. I ow think that 900 was better for that slot. Hmnn. The rest of the match had cool problems.
