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.

    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.

    I would love to solve it by dfs or bfs instead of math trick.
