链接:http://acm.hdu.edu.cn/showproblem.php?pid=4417 题意: 给你段长为n的序列,有q个询问,每次询问区间[l.r]内有多少个数小于等于k 思路: 之前用分块写过类似的,不过为了练习下主席树,这里用主席树写了下.思路很简单 离线离散化处理下,每次插入一个数num时,在主席树上下标num+1,这样每次询问[l,r]中有多少个小于k的数的时候,我们只要找下标[1,k]的区间第R次修改后的总和减去第L-1次修改后的总值就可以得到了 实现代码: #inclu…

分析:找一个区间里小于等于h的数量,然后这个题先离散化一下,很简单 然后我写这个题主要是熟悉一下主席树,其实这个题完全可以离线做,很简单 但是学了主席树以后,我发现,在线做,一样简单,而且不需要思考 (主席树大法好)无限仰慕 #include <iostream> #include <stdio.h> #include <string.h> #include <algorithm> using namespace std; ; const int INF=0…

题意:问区间内不超过k的个数 思路:显然主席树,把所有的值离散化一下,然后主席树求一下小于等于k有几个就行.注意,他给你的k不一定包含在数组里,所以问题中的询问一起离散化. 代码: #include<cmath> #include<set> #include<map> #include<queue> #include<cstdio> #include<vector> #include<cstring> #include &…
