So there's no longer t-shirt as prize(not like they actually send it anyway)?

    As per the FAQ linked above, the top 500 finishers from Round 2 will get t-shirts, as in previous years. The delivery process will also be improved to include sharing tracking numbers.

      Oh, you mean that you actually sent them last year? Oh great, now there are 475 postmen wearing FBHC shirts walking around!

      How about trying a different delivery method?

    No-shirt Cup? This sounds braver than even Wet Shirt Cup.

i think qualification round and round1 should not have such a great difference in the problem difficulty... just concerned about great number of qualifiers ...and less than half clear round 1 ...make newbies dream big and push them from high..XD

Your output is formatted incorrectly. Please make sure that you're uploading the correct file, and that you're matching the expected output format exactly.

What it is???

    I think that's because your output is formatted incorrectly.

        .txt works..

        Advice:

        I also was unsure of how to submit, so you can try to experiment a LOT with previous year problems , you can submit witout a time window there , so you can clear wall your submitting related doubts from there, thats what I did..

    ran into this problem too. I guess that's because of CR+LF line endings.

Hm, I thought problem C was as simple as looking for another occurrence of A[0] and then repeating the section from A[0] to the second occurrence, but that gave WA. Anyone wanna share the solution?

Lol my C failed because I printed "IMPOSSIBLE" instead of "Impossible".
