2018 HDU多校第四场赛后补题 自己学校出的毒瘤场..吃枣药丸 hdu中的题号是6332 - 6343. K. Expression in Memories 题意: 判断一个简化版的算术表达式是否合法. 题解: 注意细节即可. 代码: #include <bits/stdc++.h> using namespace std; int n; char s[505]; int main () { int T; cin>>T; for ( ; T; --T) { scanf(&quo…
2018 HDU多校第三场赛后补题 从易到难来写吧,其中题意有些直接摘了Claris的,数据范围是就不标了. 如果需要可以去hdu题库里找.题号是6319 - 6331. L. Visual Cube 题意: 在画布上画一个三维立方体. 题解: 模拟即可. 代码: #include <bits/stdc++.h> using namespace std; int a, b, c, R, C; char g[505][505]; int main () { int T; cin >>…
HDU 4927 −ai,直到序列长度为1.输出最后的数. 思路:这题实在是太晕了,比赛的时候搞了四个小时,从T到WA,唉--对算组合还是不太了解啊.如今对组合算比較什么了-- import java.io.*; import java.math.*; import java.util.*; public class Main { public static void main(String[] args) { Scanner cin=new Scanner (new BufferedInput…

题目链接 题意:二维平面上有n个点(没有重叠,都不在原点,任意两点连线不过原点),每个点有一个权值,用一条过原点的直线把他们划分成两部分,使两部分的权值和的乘积最大.输出最大的乘积. 极角排序后,将原来(-pi,pi]区间的元素copy到(pi,3pi],用双指针维护一个角度差不超过pi的区间,记区间的权值和为sum1,用sum1*(sum-sum)更新ans #include<bits/stdc++.h> using namespace std; typedef long long LL;…
这场就做出一道题,怎么会有窝这么辣鸡的人呢? 1001 A Boring Question(hdu 5793) 很复杂的公式,打表找的规律,最后是m^0+m^1+...+m^n,题解直接是(m^(n+1)-1)/(m-1),长姿势,原来还能化简…… 我既然不会推公式,也没啥好写的.写一下我打表的代码吧…… #include <cstdio> typedef long long ll; int n, m; ll sum; ll fac[]; ]; void init() { fac[] = ;…
