I participated in the SNUPC 2025 Div. 1, finishing in 18th place and winning a cute little 5th prize. It was a comptetion for students at Seoul National University.
Spending too much time on the easy problem C was a miss. I implemented binary walking on a segment tree using bitset knapsack, which was complete tunnel vision.
There are so many talented students at SNU. I need to work hard, too.
