I got this message when I tried to register.

Select College from given options only. If you cannot find matching College, please request for addition.

How long will it take for my college to be added? Are only graduates of those registered colleges allowed to participate?

What was the intended solution of K-star problem. I did some crap , looping over all nodes as roots. For each other, doing a BFS while keeping track of number of nodes in each root'child subtree, calculating via an k*(number of children of root) dp lmao.

Edit: And it passed.

    Yes, that seems like the intended solution. There are not that many feasible centers.

Why are codes with debug template giving me WA? This is a really annoying thing, because I have to comment off them every time I submit and vice-versa.

Does anybody know any quick work-around for this, please let me know!

    Yeah, unfortunately if you are using

    Spoiler

    Then this wont work because the ONLINE_JUDGE is not set while compiling in their OJ.
    So maybe make some LOCAL flag set while compiling in your system and change above code to this

      Thanks for your answer, but I am using an online compiler, TIO. And, I don't know what LOCAL flag is set there. However, ONLINE_JUDGE flag is not set, and that helps in debugging.
