题目链接: https://cn.vjudge.net/problem/POJ-2886 题目大意: N个人围成一圈第一个人跳出圈后会告诉你下一个谁跳出来跳出来的人(如果他手上拿的数为正数,从他左边数A个,反之,从他右边数A个) 跳出来的人所得到的糖果数量和他跳出的顺序有关 所得的糖果数为 (假设他是第k个跳出的) 则他得到的糖数为k能被多少个数整除 解题思路: 首先将因子个数打表:因子个数打表模板 然后先求出1-n中因子个数最大的为x,约瑟夫环进行x次 用线段树求出每次约瑟夫环后的具体下标.因…
题目大意:n个小孩按顺时针站成一圈,每次会有一个小孩出队(第一个出队的小孩已知),在他出队时会指定下一个出队的小孩,直到所有的小孩全部出队游戏结束.第p个出队的小孩会得到f(p)个糖果,f(p)为p的正约数个数.问获得最多糖果的小孩是谁?并求出他获得的糖果数.如果有多解,只输出最先出队的那个小孩. 题目分析:先将1~n之内的具有最多约数个数并且最小的那个数打出来,然后模拟相应的次数操作即可.模拟时利用到线段树,用线段树维护区间中有多少个小孩还没有出队,每次出队一个小孩就将他在树中删除,最后利用线…
题意:有一群小朋友围成一个环,编号1,2,3…N.每个人手上握着一个非0的数字,首先第K个人出列,然后看他手上的数字,假设为m,则从下一个开始第m个人出列,一直如此.并设i为小于等于N的最大反素数,问第i个出列的人得编号,i的约数个数.(设g(i)为i的约数的个数,若任意j<i,都有g(j)<g(i)则i为反素数). 首先要得到[0,N]的最大反素数(怎么得到下面再说),然后模拟出列操作,用线段树来优化使得每次出列在O(logN)时间内完成. #include <iostream>…
思路: 先打反素数表,即可确定因子最多的那个数.然后模拟踢人的过程确定对应的人名.模拟的过程使用线段树优化加速. 实现: #include <cstdio> #include <cstring> #include <string> #include <algorithm> using namespace std; ; , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , }…
线段树可真有意思呢续集2... 区间成段的替换和增减,以及区间求和等,其中夹杂着一些神奇的操作,数据离散化,简单hash,区间异或,还需要带着脑子来写题. 有的题目对数据的操作并不是直接按照题面意思进行操作,而是换一个角度,通过对其他数据的操作得到结果,感觉真的是...啊啊啊啊啊啊,我的脑子离家出走了,他在哪啊(ಥ_ಥ)ru 写到后面的题目就感觉满满的都是套路,只要想到怎样处理数据以及如果通过线段树维护数据就可以,但是就是这个是关键(废话...),嘤嘤嘤,一拳一个嘤嘤怪,好好写题解... POJ…

poj3159 Candies 这题实质为裸的差分约束. 先看最短路模型:若d[v] >= d[u] + w, 则连边u->v,之后就变成了d[v] <= d[u] + w , 即d[v] – d[u] <= w. 再看题目给出的关系:b比a多的糖果数目不超过c个,即d[b] – d[a] <= c ,正好与上面模型一样, 所以连边a->b,最后用dij+heap求最短路就行啦. ps:我用vector一直TLE,后来改用链式前向星才过了orz... #include&…
