Problem Description In this problem you need to make a multiply table of N * N ,just like the sample out. The element in the ith row and jth column should be the product(乘积) of i and j. Input The first line of input is an integer C which indicate the…
题意就不说了 思路:线段树,维护区间乘积.2操作就将要除的点更新为1. #include<iostream> #include<cstdio> #include<cstring> #include<cmath> #include<algorithm> #include<queue> #include<vector> #include<set> #include<string> #define inf…
[BZOJ4999]This Problem Is Too Simple!(线段树) 题面 BZOJ 题解 对于每个值,维护一棵线段树就好啦 动态开点,否则空间开不下 剩下的就是很简单的问题啦 当然了,对于数值要离散化 没必要离线吧,在线用\(map\)维护就行了 #include<iostream> #include<cstdio> #include<cstdlib> #include<cstring> #include<cmath> #inc…
BZOJ_3038_上帝造题的七分钟2_线段树 题意: XLk觉得<上帝造题的七分钟>不太过瘾,于是有了第二部. "第一分钟,X说,要有数列,于是便给定了一个正整数数列. 第二分钟,L说,要能修改,于是便有了对一段数中每个数都开平方(下取整)的操作. 第三分钟,k说,要能查询,于是便有了求一段数的和的操作. 第四分钟,彩虹喵说,要是noip难度,于是便有了数据范围. 第五分钟,诗人说,要有韵律,于是便有了时间限制和内存限制. 第六分钟,和雪说,要省点事,于是便有了保证运算过程中及最终…
