题目大意 POJ链接 给出\(n\)头牛的身高,和\(m\)对关系,表示牛\(a[i]\)与\(b[i]\)可以相互看见.已知最高的牛为第\(p\)头,身高为\(h\). 求每头牛的身高最大可能是多少. (老姚的翻译好像改变量名了昂,但是无所谓) 输入格式 第一行四个整数\(n,p,h,m\),表示见题意, 接下来\(m\)行,每行两个正整数表示\(a[i],b[i]\). 输出格式 \(n\)行整数表示每头牛的最大可能身高. 数据范围 \(1\le n\le 10000,1\le h\le 1…
一个压了很久的题目,确实很难想,看了别人的做法后总算明白了. 首先要明白一点,因为题目说明了不会有矛盾,所以题目给出来的区间是不能相交的,否则是矛盾的.(原因自己想) 然后既然区间只能是包含的,就很明显了,一个数被包含了几次它就要比最高的牛矮多少. #include <iostream> #include <cstdio> #include <cstring> #include <algorithm> using namespace std; const i…

P2879 [USACO07JAN]区间统计Tallest Cow 差分 对于每个限制$(l,r)$,我们建立一个差分数组$a[i]$ 使$a[l+1]--,a[r]++$,表示$(l,r)$区间内的数至少比$l,r$小$1$ 最后统计下前缀和,顺便把最大高度加上去. 记得判重. (逃一节晚自习真chiji) 不写了,放风时间到了. #include<iostream> #include<cstring> #include<cstdio> #include<alg…
http://www.lydsy.com/JudgeOnline/problem.php?id=1635 差分序列是个好东西啊....很多地方都用了啊,,, 线性的进行区间操作orz 有题可知 h[a+1]~a[b-1]都是比h[a]和h[b]小,那么最佳方案就是将次区间的所有高度-1,那么我们就将整个区间-1 也就是sum[a+1]--, sum[b]++ 而条件h[a]>=h[b]我还不明觉厉啊..... (脑补:假设一般情况下h[a]==h[b]的,而却有c使得(a, c), pos[c]…
