Probably, I will never understand the logic of giving 450 in Tournament rounds.
May be the logic — is to give opportunity to solve 1000.
Does anybody know if it is possible to kill 250 Java solutions which store 403 sequences in HashSet using built-in hash function? Intuitively it seems possible, however, I was not able to construct a test...
Do you mean you want to kill it using antihashmap test?
Yeah, I want to construct such a sequence, that if we remove arbitrary number and then insert some number (from the ones which are in the sequence) into arbitrary place, then we will get lots of collisions.
Well, I'm glad I used my EHashSet with random shifts
А почему решение через масштабирование выпуклой оболочки не прокатывает в 1000 (даёт ответ больше, чем у жюри)?
Upd. Фигню сказал, оно же все выпуклое.
Для выпуклых множеств это всё равно, если верить википедии. EDIT: пока я писал, ты уже исправился.
А, кажется я понял, потому что выпуклую оболочку надо строить явно, а не надеяться, что каждый "угол" будет вершиной.
Editorial
Awesome editorials.
Is it difficult to draw pictures for editorials with inkscape, such as http://apps.topcoder.com/wiki/download/attachments/108463636/3b10002.svg ?
To make a grid like that one , I just draw a single point next to a transparent square and the use the edit\clone tools.
But I think that a lot of inkscape takes practice, there I things I wouldn't have been able to do a couple of years ago.
