题目大意:有n个花瓶,每个花瓶中只能放一朵花.两种操作,一种是从A开始放F朵花,如果有的花瓶中已经有花则跳过这个花瓶,往下一个花瓶放:第二种是将区间[A,B]之间花瓶中的花清空.如果是第一种操作,输出这次放的花的左右端点:如果是第二种操作,输出这次总共清理出了多少支花. 题目分析:建立线段树,节点维护在相应的区间中,没有放入花的花瓶数目.有三种操作:一.查询某个区间中第k个没有插入花的花瓶位置:二.更新区间,使区间全部插入花:三.更新区间,使区间中的花瓶全部清空: 代码如下: # include…

分析:感觉一看就是二分+线段树,没啥好想的,唯一注意,当开始摆花时,注意和最多能放的比大小 #include<iostream> #include<cmath> #include<cstdio> #include<algorithm> #include<cstring> using namespace std; ; ],lz[N<<]; void build(int rt,int l,int r){ lz[rt]=-; ;return…

题目链接:http://acm.hdu.edu.cn/showproblem.php?pid=4614 题意: 给你N个花瓶,编号是0  到 N - 1 ,初始状态花瓶是空的,每个花瓶最多插一朵花. 然后有2个操作. 操作1,a b c ,往在a位置后面(包括a)插b朵花,输出插入的首位置和末位置. 操作2,a b ,输出区间[a , b ]范围内的花的数量,然后全部清空. 很显然这是一道线段树.区间更新,区间求和, 操作2,很显然就是线段树的区间求和,求出[a , b]范围内的花朵的数量,区间…
