解题报告 题意: 对线段染色.询问线段区间的颜色种数. 思路: 本来直接在线段树上染色,lz标记颜色.每次查询的话訪问线段树,求出颜色种数.结果超时了,最坏的情况下,染色能够染到叶子节点. 换成存下区间的颜色种数,这样每次查询就不用找到叶子节点了.用按位或来处理颜色种数. #include <iostream> #include <cstdio> #include <cstring> #include <algorithm> using namespace…

题意:给你n个球排成一行,初始都为黑色,现在给一些操作(L,R,color),给[L,R]区间内的求染上颜色color,'w'为白,'b'为黑.问最后最长的白色区间的起点和终点的位置. 解法:先离散化,为了防止离散后错误,不仅将L,R离散,还要加入L+1,L-1,R+1,R-1一起离散,这样就绝不会有问题了.然后建线段树,线段树维护四个值: 1.col  区间颜色  0 表示黑  1 表示白  -1表示无标记 2.maxi 区间内最大白区间的长度,由于白色用1表示,所以最大白区间的长度即为区间最…

本题使用线段树自然能够,由于区间的问题. 这里比較难想的就是: 1 最后更新须要查询全部叶子节点的值,故此须要使用O(nlgn)时间效率更新全部点. 2 截取区间不能有半点差错.否则答案错误. 这两点卡了我下.看来我的线段树还是不够熟,须要多多练习. 线段树是二分法的高级应用,可是却不是简单应用,要锻炼好并应用好线段树思维还是比二分法难非常多的. static const int SIZE = 100005; static const int TREESIZE = SIZE<<2; int a…
