题目大意:多组数据,每组给一个n(1=<n<=8000),下面有n行,每行有l,r,color(1=<color<=8000),表示将l~r颜色变为color,最后求各种颜色(1~8000)所占区段数,如果所占区段为0则不用输出. 解题思路:基本还是跟区间染色问题差不多,但要注意一些东西 ①这里l,r指的是端点.比如 3 1 4 1 1 2 2 3 4 3 这组数据最后输出结果为: 1 1 2 1 3 1 原因是还有[2,3]这一段颜色为1,处理办法是将更新函数写成(1,l+1,r…

题目链接 题意:成段染色,初始为0,每次改变一个区间的颜色,求最后每种颜色分别有多少段.颜色按照从 小到大输出. 分析:改变了代码的风格,因为看了学长的博客.直接用数组,可以只是记录节点的编号,因为节点编号 确定了,则l,r也就确定了. #include <iostream> #include <cstdio> #include <vector> #include <cstring> #include <cstdlib> #include <…

1.给了每条线段的颜色,存在颜色覆盖,求表面上能够看到的颜色种类以及每种颜色的段数. 2.线段树区间更新,单点查询. 但是有点细节,比如: 输入: 2 0 1 1 2 3 1 输出: 1 2 这种情况如果不处理,那么由于是检查点的颜色,会检查到0,1,2,3的颜色都为1,认为是一段连续的,就会输出 1 1 需要处理一下,代码中把所有的左端点都+1,避免了这种情况,比较巧妙. 3. #include<iostream> #include<stdio.h> #include<st…

题目链接 题意 : 一根木棍,长8000,然后分别在不同的区间涂上不同的颜色,问你最后能够看到多少颜色,然后每个颜色有多少段,颜色大小从头到尾输出. 思路 :线段树区间更新一下,然后标记一下,最后从头输出. //ZOJ 1610 #include <cstdio> #include <cstring> #include <iostream> using namespace std ; *],lz[*] ,hashh[*],hash1[*]; //void pushup(…
