开场猜J可以暴力，写了一下，果然跪了……[[BR]]
换高斯消元，搞了快一个小时才把方程组建对。'''J4y110'''[[BR]]
然后跟sf说了B的做法，让他上去写[[BR]]
刚不过F题的数据结构，含泪收场……[[BR]]

=== sfiction ===

开场A题打了一下表，出现的规律太过优美以至于又验证了一会儿。'''A1y2'''。[[BR]]
之后我看了看D，没过多久D已经被万人轮了。然而我花了一个多小时才确认了贪心。感觉自己的智商也是低得不行。'''D1y106'''。[[BR]]
之后我看了看其他题目，感觉B是道网络流，wxj学长建好图之后我开始抄模板。因为看错一处题目细节和看错输出格式获得WA和PE各一个。'''B3y208'''。[[BR]]
最后试图做出F，失败告终。[[BR]]

=== JTJL ===

At the begining of the contest, we guessed the pattern of the problem A and soon got AC.[[BR]]
Then I read the problem E. Aha, a stupid DP! But I thought the accuracy will BOOM, so I decided to use JAVA. Just at the time I opened eclipse, Patchouli asked me to notice the Hint: "Log is Useful." Actually, I think the word "log" meant "journal" but not "logarithms" before he told me.....= =.'''E1y85'''[[BR]]
After that, I read problem I. Firstly, I decided to use segment tree to maintain the process, and calculate the answer with the combination, ans its' time complexity was O(nlogn), SCIENTIFIC! But soon, I optimized my algorithm and decrease the time complexity to O(n)...I was too scaried to write this program because it worked too fast...[[BR]]
But the computer was spare at that time, so I wrote it. After three times Wrong Answer, I got AC at last.'''I4y214'''.[[BR]]
