One day there was discussion that we need a way to recognize variants of “sbsa-ref” in some sane way. The idea was to get rid of most of hardcoded values and provide a way to have data going from QEMU up to firmware. We started with adding “platform version major/minor” fields into DeviceTree. Starting with “0.0” as value. And for some time nothing changed here as some of people working on SBSA Reference Platform changed jobs and other worked on other parts of it. Note that this is different than other QEMU targets. We do not go “sbsa-ref-8.0”, “sbsa-ref-8.1” way as this would add maintenance work without any gain for us. During last Linaro Connect we had some discussion on how we want to proceed. And some after (as not everyone got there — UK visa issues).

有一天，我们讨论了一下需要以某种合理的方式识别“sbsa-ref”的变体。这个想法是为了消除大部分硬编码的值，并提供一种从QEMU到固件的数据传输方式。我们从在DeviceTree中添加“平台版本major/minor”字段开始。初始值为“0.0”。一段时间内，这里没有发生任何变化，因为一些参与SBSA参考平台开发的人员换了工作，其他人则负责其他部分的开发。请注意，这与其他QEMU目标不同。我们不会采用“sbsa-ref-8.0”、“sbsa-ref-8.1”这样的方法，因为这会增加我们的维护工作，没有任何好处。在最近的Linaro Connect会议上，我们讨论了如何继续进行。但由于有些人无法出席（由于英国签证问题），所以讨论还在继续。

1444. Elephpotamus Time limit: 0.5 second Memory limit: 64 MB Harry Potter is taking an examination in Care for Magical Creatures. His task is to feed a dwarf elephpotamus. Harry remembers that elephpotamuses are very straightforward and imperturbable. In fact, they are so straightforward that always move along a straight line and they are so imperturbable that only move when attracted by something really tasty. In addition, if an elephpotamus stumbles into a chain of its own footprints, it falls into a stupor and refuses to go anywhere. According to Hagrid, elephpotamuses usually get back home moving along their footprints. This is why they never cross them, otherwise they may get lost. When an elephpotamus sees its footprints, it tries to remember in detail all its movements since leaving home (this is also the reason why they move along straight lines only, this way it is easier to memorize). Basing on this information, the animal calculates in which direction its burrow is situated, then turns and goes straight to it. It takes some (rather large) time for an elephpotamus to perform these calculations. And what some ignoramuses recognize as a stupor is in fact a demonstration of outstanding calculating abilities of this wonderful, though a bit slow-witted creature. Elephpotamuses' favorite dainty is elephant pumpkins, and some of such pumpkins grow on the lawn where Harry is to take his exam. At the start of the exam, Hagrid will drag the elephpotamus to one of the pumpkins. Having fed the animal with a pumpkin, Harry can direct it to any of the remaining pumpkins. In order to pass the exam, Harry must lead the elephpotamus so that it eats as many pumpkins as possible before it comes across its footprints. Input The first input line contains the number of pumpkins on the lawn N (3 ≤ N ≤ 30000). The pumpkins are numbered from 1 to N, the number one being assigned to the pumpkin to which the animal is brought at the start of the trial. In the next N lines, the coordinates of the pumpkins are given in the order corresponding to their numbers. All the coordinates are integers in the range from −1000 to 1000. It is guaranteed that there are no two pumpkins at the same location and there is no straight line passing through all the pumpkins. Output In the first line write the maximal number K of pumpkins that can be fed to the elephpotamus. In the next K lines, output the order in which the animal will eat them, giving one number in a line. The first number in this sequence must always be 1.写一段Java完成此目的

题目翻译：哈利波特正在参加魔法生物关怀考试，他的任务是喂养一只小矮象河马。小矮象河马非常直接和冷静，只有在被真正美味的东西吸引时才会移动。此外，如果小矮象河马跌入自己的脚印链中，它会陷入昏迷并拒绝前进。根据海格的说法，小矮象河马通常沿着自己的脚印回家。这就是为什么它们从不越过脚印，否则它们可能会迷路。当小矮象河马看到自己的脚印时，它会尽力记住自离家出发以来的所有行动，然后计算出其巢穴的方向，然后转身朝着巢穴直走。一个小矮象河马执行这些计算需要一些时间。而一些无知的人认为这是一种昏迷，实际上这是这种美妙的，虽然有点迟钝的生物出色的计算能力的展示。小矮象河马最喜欢的美食是大象南瓜，而哈利所在的草坪上就有一些这样的南瓜。在考试开始时，海格将小矮象河马拖到其中一只南瓜旁边。喂了小矮象河马一只南瓜后，哈利可以把它引导到剩下的任意一只南瓜。为了通过考试，哈利必须引导小矮象河马尽可能多地吃南瓜，直到它遇到自己的脚印。

输入：第一行包含草坪上南瓜的数量N（3≤N≤30000）。南瓜从1到N编号，数字1被分配给小矮象河马开始时所在的南瓜。在接下来的N行中，按其编号对应的顺序给出南瓜的坐标。所有坐标都是范围从-1000到1000的整数。保证没有两个南瓜在相同的位置，并且没有一条直线穿过所有南瓜。

输出：第一行写出小矮象河马最多可以吃到的南瓜数K。在接下来的K行中，输出小矮象河马将要吃的南瓜的顺序，每行输出一个数字。这个序列中的第一个数字必须始终为1。

解题思路：这道题是一道比较难的贪心算法，需要仔细思考。我们可以先把所有的南瓜按照离开始点的距离排序，然后从第二个南瓜开始遍历，每次找到一个能够吃到的南瓜就将其加入结果中，并更新当前位置和能够到达的最远位置。如果当前位置已经在之前的路径中出现过，那么就不能再继续走了，因为这样会导致小矮象河马迷路。最后输出结果即可。

Recently, the renowned actor Zhang Songwen has sparked a fascinating phenomenon known as "two-way rejection", which has captured the attention of many and inspired the masses. The roots of this phenomenon are complex, with one of the fundamental causes being the fear of failure that plagues most of us. Rejection can instill a sense of inadequacy and a fear of being perceived as a failure, which can be challenging to overcome. However, the concept of "two-way rejection" teaches us that rejection is a natural part of life, and it's acceptable to reject and be rejected in return. This empowers us to recognize that life is not just about failures, but also about perseverance, and striving to achieve our aspirations, which may include fame and fortune. Despite the distractions we may encounter, the concept of "two-way rejection" reminds us to turn away from erroneous opportunities and remain steadfast in our principles and moral compass. While there are both advantages and drawbacks to this approach, "two-way rejection" ultimately inspires us to embrace rejection, learn from it, and emerge stronger and more self-assured. However, it is essential to distinguish between a sound and an unsound opportunity to avoid blindly rejecting the right ones. In conclusion, the concept of "two-way rejection" should be approached with discretion, but it can prove to be a valuable tool in enabling us to adhere to our goals and persevere through rejection. It teaches us to embrace rejection, learn from it, and move forward with confidence, ultimately empowering us to achieve our dreams and aspirations.结合双向拒绝进行内容补充

The concept of "two-way rejection" is not only about rejecting others but also about being willing to accept rejection ourselves. It encourages us to be open to constructive criticism and feedback, which can help us improve ourselves and our skills. By embracing rejection, we can learn from our mistakes, understand our weaknesses, and work on improving them.

Moreover, "two-way rejection" also emphasizes the importance of communication. It is essential to communicate effectively and honestly with others, whether we are rejecting them or being rejected. We must be respectful and considerate of other people's feelings while also being true to ourselves and our goals.

Another aspect of "two-way rejection" is the idea of resilience. It is about bouncing back from rejection and not letting it define us. When we face rejection, it can be tempting to give up and lose hope, but by embracing "two-way rejection," we can develop resilience and determination to keep pushing forward.

In summary, "two-way rejection" is a powerful concept that can help us overcome the fear of failure and embrace rejection. It encourages us to communicate effectively, be open to feedback, and develop resilience in the face of rejection. By adopting this approach, we can become more self-assured and empowered to achieve our dreams and aspirations.
