近期情绪太不稳定了.可能是由于在找实习这个过程碰壁了吧.第一次面试就跪了,可能是我面的是一个新公司,制度不完好,我感觉整个面试过程全然不沾编程,我面试的还是软件开发-后来我同学面试的时候.说是有一道数学题了.最后都已经签了,orz...其它同学都陆续签了,有签了知乎.有签了猎豹的,有签了阿里的,我还在想着打比赛,作为一个快大四的人.我还想着打比赛.甚至我连队友都快没了-可是我还想坚持!到如今,我基本没课了,每天都仅仅能是刷刷题,写写python,搞搞shell,我都不知道我在干嘛-!有没有大神给…

http://acm.hdu.edu.cn/showproblem.php?pid=1506 题意:给出n个矩形的高度,每个矩形的宽都为1,求相邻的矩形能组合成的最大的矩形的面积. 思路:求出比第i个矩形大的最左边的矩形的位置 l[i], 及比第i个矩形大的最右边的矩形的位置 r[i], 则第i个矩形的面积 s = (r[i]-l[i]+1)*hign[i]. 如果第i-1个矩形比第i个矩形大,则 l[i] 必定在 l[i-1]的 左边,同理,r[i]必定在 r[i+1]的右边. #includ…

                                     Largest Rectangle in a Histogram 这么经典的题硬是等今天碰到了原题现场懵逼两小时才会去补题...废话不多说: 题意:截取一个矩形使其面积最大,随你怎么截,反正面积要最大.输出最大面积,注意爆int. 思路:dp或单调队列.核心思路是从一个小矩形往两边扩散,分别找两边第一个小于这个矩形的位置,其中面积就是这个小矩形与区间长度的乘积,我们预处理出所有的小矩形的这两个端点值,然后扫一遍即可更新到最…
