I started using TopCoder Web Arena to upsolve older SRMs, since moving to a new practice room takes too long while using Java Applet (could be my Internet issue).

Here's the problem. Large integers (about $$$10^{16}$$$) can't be shown correctly in the Web Arena.

Example:

And as you can see, the verdict shows N/A instead of Correct or Wrong Answer. It's very weird.

Be aware of this hmehta.

Sorry for asking here but, how do you even use the Web Arena? I wanted to give TopCoder a try but when I click practice problems it says 'Failed to get practice problem: cannot connect to server', so I assumed nobody could use it, but now I see this post...

I can confirm that it's not an internet issue, it's just topcoder being shit.

"moving to a new practice room takes too long while using Java Applet" This also happened with me. I waited almost 1 hour for moving into a pratice room once.

I solve older SRM's by creating contest ownself in Vjudge. The problem number for creating contest in Vjudge can be found from here:

https://www.topcoder.com/tc?module=ProblemArchive

Click in a problem and you will find the number from the link of the problem. You can also find specific SRM's by searching google normally.

This long process is painful sometimes but Topcoder's problems are good :)

    You can also search for the problem title (main class name of solution in TopCoder) to find the specific problem.

    Well you can't see system test details in vjudge.

      Yes. But it saves time rather than using Web Arena.

    You can also find specific SRM's by searching google normally.

    Also you can use clist.by to search for а topcoder problem by name or to search for a specific competition.

    Usually I just wait ~$$$10$$$ mins, and if it still hasn't moved me by then, I just restart the applet and then it moves me like almost instantaneously, pretty weird.
