Each input file will not be larger than 4 MB (4,000,000,000 bytes) in size.

Do MB mean gigabyte in India? :)

It is always nice to solve 4 problems within 18 minutes, but not so not being able to submit all of them within 44 minutes :(

    We had a bad SYN attack once again due to which the site was terribly slow. We are embarrassed to say the least. Now things should be fine. We shall be extending the contest by 45 minutes. We are sorry.

      The annoying thing is that there is a bug that doesn't get fixed where submissions get blocked. This happened to me last 2 cook offs, not on this one, but by reading announcements it seems you have a problem.

      The another annoying thing is getting used to SPOJ's slow computers.

      Due to such serious networking issues, it's rather reasonable to make this contest unrated.

    Сортим ребра шефа по убыванию, остальные — по возрастанию. Набираем начиная с ребёр шефа как в алгоритме Крускала.
    UPD и ветка не английская.

    Сначала строить максимальное остовное дерево на M2 ребрах, а потом строить осташийся кусок минимального остовного дерева на M1 ребрах.
