题意:给你一个序列,长度不超过52,每个元素不超过13.让你重新对这个序列排序,sum(i)表示i的前缀和,使得排序过后,对每个i,都有sum(i)%i==0. 深搜,加两个优化:①倒着从后向前搜:②枚举的时候不要枚举52个,而枚举值域(只有13),能快一点. 另外,一开始想的是相同的元素在最后一定都相邻,但是事实上试了试之后发现不行. #include<cstdio> #include<cstdlib> using namespace std; int path[60],a[60…

Summary 今天比赛很差很差,掉到谷底.第一题快排打错了,漏了递归,变成一个while循环.最后一题k忘记减一,答案一直是无穷大,所以没交.第三题没时间调DP就打了个递归,第二题状态想歪了.四道题有三道DP的,一道小码力的.DP可见很差,还要多学,多做.快排打到一半傻乎乎就没打了,样例数据又刚好都是对的,不会对拍.马上就要学一下啊! Problem T1 平台 题目大意 给你一堆平台,每个平台平行于x轴,距离x轴有个高度h.每个平台由两个柱子支撑,分别在离端点0.5个单位的位置.问柱子的长度…
