第二阶段总结 2013年的暑假即将结束，这一个暑期来学到了不少东西，但是还有很多东西还不会，算一个遗憾吧。 在第二阶段开始时，进行了两次个人赛，然后进行了分组训练，虽然成绩不太稳定，但是还是写了不少题。第一次使用了搜索，第一次使用sscanf，接触了很多新的知识，但是依旧对数据结构这方面的只是欠缺，我会在开学补上来的。下面是暑期第二阶段的训练情况。 -----------------

暑期第一阶段总结 第一阶段已经结束一周了，由于前段时间由于种种原因忘记写总结了，今天特来补上。 暑期第一阶段培训，感觉收获还是比较大的，学会了不少算法，当然数据结构的算法由于个人原因就没去看过，所以导致现在还没学习数据结构的算法。在暑期自修的这段时间还是巩固第一阶段所学的算法，然后学习下新算法，为暑期第二阶段做准备。 -------------------------

题目略，题目传送门http://acm.hust.edu.cn/problem.php?cid=1106&pid=7。 解题报告 此题意思不难懂，就是拿一张纸，左右折，上下折，计算出有几条线段是凸出来了。第一次不论怎么折都是0条，然后能找出一个规律。就是记录左右和上下折的次数i,j(不包含第一次)，所以ans=(2^i-1)*2^j+(2^j-1)*2^i.代码如下： #includ
