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 >>…
对于 D 题的原题意,出题人和验题人赛前都没有发现标算存在的问题,导致了许多选手的疑惑和时间的浪费,在此表示真诚的歉意! 预计难度分布: Easy - DJKL, Medium - ABCEG, Hard - FHI A. Integers Exhibition 不难发现非 \(K\)-magic 数是非常少的,考虑先预处理出来,二分回答询问. 以下我们讨论如何求出非 \(K\)-magic 数,为方便描述,我们称一个正整数是良好的当且仅当其是非 \(K\)-magic 的. 对于一个质数 \(…
6336.Problem E. Matrix from Arrays 不想解释了,直接官方题解: 队友写了博客,我是水的他的代码 ------>HDU 6336 子矩阵求和 至于为什么是4倍的,因为这个矩阵是左上半边有数,所以开4倍才能保证求的矩阵区域里面有数,就是图上的红色阴影部分,蓝色为待求解矩阵. 其他的就是容斥原理用一下,其他的就没什么了. 代码: //1005-6336-矩阵求和-二维前缀和+容斥-预处理O(1)查询输出 #include<iostream> #include&…
