I think July Long had some nice problems (the mathy one was September Long).
I tried to make the contest more balanced. As all things should be.
Also Arjun helped me not choosing too hard cakewalks :stuck_out_tongue:

In tourist style:

I enjoyed the contest in general but the delicious touch was in Pretty Boxes: … “Don’t ask why a box can fit into another box with the same size” :clap: :clap:

“A stack of 100’000 boxes! You shouldn’t have!”

Also amusing that giving her 0 boxes - i.e. nothing at all - counts as a present :slight_smile:

Is the test in DDART just weak or my assumption is correct? “The point that every circle passes through have integer coordinates”.
I was generating tests to test my solution and realize it would be hard to do a big test with non - integer coordinates for center and everything else integer, or impossible, but didn’t prove it. Though my asserts passed so I just went along with it. Maybe the problem setter is lazy (well, the problem is identical to a Chinese one I did a few months ago anyways, just increased limit and made the people have to find the middle point).

don’t think about it!

what is going on…is it really 1400 or 140?

Just Kidding

The problem PHCUL had pretty weak tests. Something should be done about it. Please refer to this thread.

I’ll ask the setter to add more test data to the practice section.
