First
It's very good to see a new writer in TopCoder SRM. Good luck laoriu for the contest!
Thank you! Hope I''ll hear some good feedback after the contest ended.
Have you guys any plan to update the topcoder applet? As we are heading for 2021, it's too boring to use that...and when I use topcoder arena, I feel like I'm using 2G internet. It's too much slow to load.
It would be great if you guys upgrade the platform first and then arrange a contest.
I mean, TopCoder arena sucks of course, but "too boring"? Do you only like websites with fancy UIs?
Actually, I think competing on TopCoder is very interesting! You never know what will break this time.
Topcoder will die very soon.
Just look at the numbers of upvotes this blog is getting. Also the number of participants are decreasing. All because of shit interface.
Looks matters.
nice div 1 500. Can anyone please explain their solution.
Dp with $$$3^n$$$ states. In a state you keep for each vertex information whether it was already processed, and if it was, whether it already got correctly computed distance at the time it was processed.
Wow this idea is very new to me.. Thanks:)
I am actually happy that I participated, I found 500 and 1000 really nice
What a Div2 Easy problem...
I would love to solve it by dfs or bfs instead of math trick.
