<p>废话少说直接上图（...）</p>

<p>什么？我在哪个队里？当然是那个没有楼上的队了……（都怪我们队的大神(tui)yxz要取这么一个队名）</p>
<p>总之，水过去了……</p>
<p>
简单写一下题目思路……
</p><ul>
<li>A: 嗯这是个好题（呸）……注意good morningood morning的情况就好了。</li>
<li>B: 暴搜（yxz神犇要写非常厉害的状态存储方式……）</li>
<li>C: 语文题 模拟……（全场就我们一个队过了这题也是非常奇怪的事情）</li>
<li>D: 暴力会T……然后我们很容易能发现加起来的一串数是有周期的 T=lcm(a,b)</li>
<li>E: 博弈论 这题应该算是瞎猫撞上死耗子了……puts(!(n&1)&&!(m&1)?"A...":"D...")</li>
<li>F: 又是一道语文题 然而其实还是暴力……（Naive的我还以为这题会因为浮点数操作太多而T掉QAQ）</li>
<li>G: 这题跟SDTSC 2014 R2某题几乎一样，不过数据比较水，所以也不用什么加了特技的高斯消元，搞出矩阵然后暴力高斯消元就好了（然而最后高斯消元没打出来………瞬间感觉渣爆了）</li>
<li>H: 新生组就是这么多暴力题……</li>
<li>I: 多边形面积……从一个点切成一堆三角形然后叉积。嗯好高中的东西大概还没忘光</li>
<li>J: 这题的关系网其实是一棵树 然后就是类似dp的东西……（然而由于当时意识模糊WA掉了。。。）</li>
<li>K: 找a/b的最大值……每次最后一题都一定是水题吗。。。</li>
</ul>
<p></p>
<p><s>听说有学长放言如果有队伍AK就直播日狗，没能满足他的愿望，真是抱歉（……）</s></p>
<p>
然后最近其实有点忙，再加上等新笔记本<s>（借口）</s>，所以感觉有些方面还是努力不够……
</p>
<p>
<reduced><s>
（于是看新笔记本到了之后我又会编出什么新的借口）
