UVA 11610 Reverse Prime (数论+树状数组+二分，难题)

参考链接http://blog.csdn.net/acm_cxlove/article/details/8264290http://blog.csdn.net/w00w12l/article/details/8212782 题意: 首先定义了一种叫做Reverse Prime的数:是一个7位数,倒置后是一个<=10^6的素数(如1000070) 然后要把所有的Reverse Prime求出来,排好序. 然后题目有2种操作: q x :求编号0到编号x的Reverse Prime的质因数个数的和…

HDU 4746 莫比乌斯反演+离线查询+树状数组

题目大意: 一个数字组成一堆素因子的乘积,如果一个数字的素因子个数(同样的素因子也要多次计数)小于等于P,那么就称这个数是P的幸运数多次询问1<=x<=n,1<=y<=m,P , 找到多少对gcd(x,y)是P的幸运数这里k定为k是P的幸运数这跟之前做的http://www.cnblogs.com/CSU3901130321/p/4902748.html CSU1325的题目很像,但是这里求sum[]要复杂了很多本来是枚举k,d求sum的,但是每次询问,P都在变,而我们需要…

bzoj3529(莫比乌斯反演＋离线＋树状数组)

在你以为理解mobus的时候,苦苦想通过化简公式来降低复杂度时,这题又打了我一巴掌. 看来我并没有理解到acmicpc比赛的宗旨啊. 这么多次查询可以考虑离线操作,使用树状数组单点更新. /************************************************************** Problem: 3529 User: chenhuan001 Language: C++ Result: Accepted Time:5264 ms Memory:8412 kb *…
