id="more"></span><h2 id="day-0"><a class="markdownIt-Anchor" href="#day-0"></a> Day 0</h2><p>首先交代一下概况～</p><p>坐标 SH ，全国少数采用上机考试的城市之一</p><p>今年报名人数3000+，比去年多了1000多人（不过来打酱油的小学生很多…）</p><p>然后咱高中是今年上海的几个 CSP 认证点之一～在自己学校的机子上考真好～</p><p><s>闲得无聊</s>翻着考场名单突然发现某沪上知名 OI 教练竟然真的报名参加 CSP-S ？！</p><p>今年机考其实是可以用 DEV-C++ 的！特派员来我们学校的时候还特别说过…</p><p>考试前一天晚上刚从东方绿舟军训回来…虽然累炸了还是做了套某机构出的纯选择题的模拟题，大概75左右，稍微松了口气</p><p>然后就是特意把图论的最短路算法、二叉树的性质和遍历、深搜广搜、链表、指针以及计算机基础常识复习了一遍，最后才睡觉</p><h2 id="day-1"><a class="markdownIt-Anchor" href="#day-1"></a> Day 1</h2><p>因为就在自己学校考不算很远，睡了个小懒觉才起床…</p><p>状态不错地提前45分钟到达学校，老师让咱先去科技楼一楼某教室等着…然后我才知道一楼角落里藏着的某个不起眼的教室居然配备了一堆高配电脑？？？一群高二的巨佬正在打游戏…</p><p>拿出手机上洛谷求了个签，大吉～宜参加 CSP ，RP++ ，宜泡妹子（？！）</p><p>不过咱机房有人开出『吉，宜丧葬』的…感到大事不妙</p><p>等了大概半小时上楼到机房，监考老师是个大学生小姐姐～拿着似乎没啥用的金属探测仪给每个人扫了一遍（每个人都会响…）</p><p>坐到电脑前，发现电脑不知被动了什么手脚，竟然比平时卡了不少…屏幕右下角的电子监考系统居然是灰色的未启用状态，老师全程硬核人工＋极域监考…硬盘和U盘倒是做了屏蔽工作，网页的屏蔽用的貌似是极域，并没有用到什么物理防火墙…</p><p>环顾一下考场确实有很多小学生…</p><p>然后开考前五分钟老师公布考试网址并下发密码条，不过她还没等我们反应过来就拿起墨水的白板笔往机房的电子白板上写…全然不知头顶上为什么会有个短焦投影机…目测应该是毁了电子白板…</p><p>输入网址回车，盯着 Chrome 选项卡上不停旋转的圈圈，我有种不详的预感…</p><p>果不其然，CCF 的姥爷机爆炸了！</p><p>在全国各地考生的帮助下，CCF 完成了 CSP (CCF Server Pressure test) 并拒绝了所有请求</p><p>当然机房里也有那么一两个幸运儿能够顺利登录，但是题目也加载不出来</p><p>等了20多分钟终于咱信息老师冲进机房说换服务器了…我抬头一看…woc这不就是模拟赛的服务器地址嘛…</p><p>这次终于登上去了，开始做题～</p><p>考试系统长这样：</p><p><img

年前的风格啊喂</p><p>关于题目后面再说…</p><p>开考后过了没几分钟，我明显感受到我左侧机位坐着的小学生已经坐不住了…果然小学生多数都是来打酱油的2333333</p><p>由于服务器的故障考试延期到11:55交卷，还算厚道，不过提交时依然很堵塞，还有人提交的时候要求重新登陆，登陆完发现答案全没了（太惨了）</p><p>我卡着点交了卷走人～</p><p>出了考场看了知乎和洛谷才知道 SH 很多考点考生都不敢用 DEV ，幸好咱老师明确说过可以充分利用网络外的一切功能，赚到了～</p><p>然后来说说题目吧…就是这次初赛我死得很难看，爆零预定(x)</p><p>『十年OI一场空，一道状压见祖宗』</p><p>考前我觉得dp不会考，而且我也没学过，没想到选择题考了一道，压轴题又考了一道状压…只好全蒙A（为什么不蒙C呢？因为希望这题能 AK ～）</p><p>然后弗洛伊德不贪心…掉坑（本来选了弗洛伊德算法后来犹豫不决改 Prim 算法然后错了…）</p><p>无向<strong>非</strong>联通图再次掉坑…</p><p>字符串处理题完全看不懂在干啥，不过 cin 不能读入空串倒是考虑到了…</p><p>车牌号那题想了好久没做出来，也是瞎猜的</p><p>当然这次初赛里也有几道原题，考前在军训的时候把 2008-2018 NOIP 初赛都刷了一遍，还是挺有帮助的</p><p>可惜我复习到的二叉树遍历、指针链表完全没考…计算机基础知识也基本没有涉及…</p><p>当晚民间答案估分60左右，不知道 SH 分数线咋样（感觉可能要 AFO 了）</p><h2 id="20191028"><a class="markdownIt-Anchor" href="#20191028"></a> 2019.10.28</h2><p>从24日开始，部分省份已经陆陆续续地开始公示成绩了，然而 SH 却迟迟不肯放出成绩</p><p>27日晚，我又反复刷了几遍 NOI 官网，却依旧没有新的通知…</p><p>28日早再次查看依然没有…</p><p>28日中午在学校吃完饭，想用教室的电脑查成绩，发现 NOI 网站…它…它居然关服了？!</p><p>于是乎吃完晚饭晚自修还没开始，我又查了一下，终于… SH 出现在了列表里！</p><p>心情真的是特别忐忑，在巨长的名单里翻了20多页找到了自己的考号…</p><p><img src="https://hans362-img.oss.0vv0.top/2019/11/03/IMG_20191102_214811.jpg?width=1920" class="lazy"

分数线在30多分，今年这全部选择题的架势感觉分数会涨不少，结果也并没有上升多高…</p><p>进入第二轮一共约900人，我排位已经到300名开外了…不过低分飘过也是很不错的了…</p><h2 id="总结"><a class="markdownIt-Anchor" href="#总结"></a> 总结</h2><p>作为 CSP-S 第一届的参赛者，以我的角度写了这篇游记～</p><p>希望明年
