说实话我觉得做这种题很没意思(不够硬核), 可是人有短板终究是要补的...起码这种类型补起来相对简单 所以还是把先前准备好的专题放下吧,做点实现上比较休闲的题 ps.为了精简篇幅,代码全部丢到ubuntu上 Codeforces - 483C 题意:给定\(k\),构造\(n\)的某一排列\(p\)满足\(|p_i-p_{i+1}|\)共有\(k\)种不同的值 做法:当\(k\)为\(n-1\)时,分奇偶前后插可满足情况,\(k<n-1\)时从\(k\)处开始排序可消除差异 https://pa…

今天下午先写一个Splay水题来复习一下Splay模板.是不是有点太水了做这种水题我有点良心不安. 可笑的是一开始我竟然WA了一组,看来是我低估水题的数据范围了,我是空节点直接返回inf或-inf,明显是不合理的.比赛时再犯这种低级错误就真的滚粗了. 2016-07-29 当时我确实狂妄自大~~~~(>_<)~~~~ #include<cstdio> #include<cctype> #include<cstring> #include<algorit…
